Multilateral trading facilities are also required to provide pre- and post-trade transparency. The result of this is that orders and quotes are visible on a data feed before trades are executed – enabling users to select the best available prices for their trade volumes – while executed orders are published as close to real time as technically possible. Pre- and post-trade information is publicly available.

A regulated market (RM) is a European multilateral trading venue where contracts for the exchange of financial instruments are formed. They are very similar to multilateral trading facilities because – under MiFID II rules – both can offer equities and non-equities, must execute orders on a non-discretionary basis, and are prohibited from using proprietary capital or engaging in matched principal trading.

As such, there is a level playing field between RMs and MTFs – both are neutral venues that provide a high level of transparency and supervision.

The main difference between a regulated market and an MTF is that an RM can only be run by a ‘market operator’, which must achieve this status by subjecting its management team and structure to the scrutiny of the EU member state in which it is based. MTFs, in contrast, can be set up by either a market operator or an investment firm.

Block then utilizes its unique laser capabilities as the basis for broad spectral analyzers for a variety of gas, liquid, and surface detection applications. In these systems each laser pulse is monitored by built-in, unique, high-speed detectors and electronics, which analyze it after its interaction with the substances under investigation and the algorithms convert the measurements into infrared spectra. Built-in libraries analyze these spectra, account for background interferences and provide identification of the substance. The QCLs operate typically in the 200 kHz range and all data processing is performed in real time, enabling sub-second measurements.

MTF BedeutungOptik

Many of the financial instruments available on MTFs can be listed elsewhere – for example, on traditional exchanges. It is also worth noting that securities can be made available for trading across multiple MTFs, which has led to greater fragmentation of the financial markets in Europe and increased competition.

They operate under the European Union’s (EU’s) Markets in Financial Instruments Directive II (MiFID II), which stipulates that financial instruments traded via an MTF must be exchanged on a ‘non-discretionary basis’. This means that contracts between buyers and sellers must be formed according to a set of transparent rules that do not discriminate between members or their clients.

Block is using pulsed Quantum Cascade Lasers in a grating-based, External Cavity configuration under various designs. Block’s integrated laser systems offer continuous tuning anywhere between 5.4 - 12.8 µm, the widest tuning range in a compact fully integrated system commercially available today.

What doesMTFmean on instagram

QCLs are semiconductor devices, which operate differently from conventional semiconductor lasers. In general, a semiconductor material absorbs photons when excited electrons move from the valence band into the conduction band (leaving positive "holes"). In reverse, photons are emitted when electrons drop into the valence band and eliminate the "holes". In conventional semiconductor lasers, these actions occur in the "active region", which is typically a two-layer structure of different semiconductor materials, forming a p-n junction.

MTFs generate revenue by charging the members that use the venue. These financial institutions, in turn, generate revenue predominately from the spread and commissions charged on trades. This structure ensures that there is no conflict of interest between the end trader and the MTF.

This operation of the Block spectrometers is often called "pre-dispersive spectroscopy", since light is split into the various wavelengths (i.e. each laser pulse corresponds to a different wavelength) prior to its interaction with the target substance. Such operation offers very narrow spectral linewidths, as narrow as 0.1-0.5 cm-1, which enable high resolution spectral measurements, especially for gases or substances that have spectral features too close to each other.

Block has used its decades-long experience with infrared spectroscopy and system-level packaging to develop complete systems that are capable of detecting and identifying substances. Even though the heart of the Block systems is the QCL, thermal stabilization, elimination of environmental interferences, algorithmic analysis and telecommunications-type of packaging expertise have all contributed to the development of the laser-based systems offered by Block today.

As an example, these rules could be based on the time and price at which orders and quotes are entered into the system. MTFs are not permitted to execute client orders against their own capital or engage in matched principal trading – they are simply a venue where buyers and sellers are paired.

Specially designed cladding layers around the active region constrain the generated photons, which are forced to bounce between two specially coated facets that act as the traditional mirrors of a laser cavity. The wavelength of the emitted light is determined by the "energy gap" between the valence and conduction bands of the semiconductor material, which is predetermined and it is controlled by the optical properties of the semiconductor material. Therefore, the wavelengths can only be changed by selecting different materials, a process that is not easy in general.

OTFs are a type of European multilateral trading venue where contracts for the exchange of non-equities such as bonds, structured finance products, emission allowances or derivatives are formed.

The main difference between OTFs and MTFs is that the former can only offer non-equities, whereas MTFs can offer equities and non-equities. An OTF can also only be operated by an investment firm, while an MTF can be run by an investment firm or market operator.Additionally, orders executed on an OTF are carried out on a discretionary basis, unlike MTFs where buyers and sellers must be matched according to non-discretionary rules. OTFs are also allowed to engage in matched principal trading on instruments that aren’t subject to the clearing obligation set out in the European Market Infrastructure Regulation (EMIR), provided they have client consent to do so.Finally, OTFs are authorised to deal bonds against proprietary capital and on their own account, with this regulation reflecting the fact that the sovereign debt markets are often illiquid.

One of the key breakthroughs in the development of QCLs has been the availability of Molecular Beam Epitaxy (MBE) machines, which have enabled the growth of thin layers with dramatic precision and control. These machines are now considered mature and reliable and the QCL manufacturers have been using them routinely. Furthermore, over the past few years, unique coatings technologies have been developed and perfected, allowing the deposition of such coatings on the facets of the lasers with impressive optical properties and operational reliability. QCLs today are used in both pulsed and continuous wave (CW) modes of operation, each one offering specific advantages depending on the particular application.

Block Engineering's laser-based products utilize next generation quantum cascade lasers (QCLs) and infrared absorption spectroscopy. QCLs were invented and first fabricated at Bell Laboratories in the late '70s by Federico Capasso, Jerome Faist and their colleagues, but their wide use for applications outside the laboratory is much more recent.

In contrast to the above described conventional semiconductor lasers, the QCLs rely on the emission of photons only within the conduction band. Electrons "cascade" from higher to lower energy levels of quantum wells within the band and as they do so, photons are emitted. This process generates wavelengths that are now controlled only by the thickness of the quantum-well layers. Therefore, the emitted wavelengths can be designed to fall within essentially any region of the mid- and far-infrared spectrum by controlling the thickness of the layers, rather than the specific optical properties of the semiconductor materials.

Brokers, market makers, banks, hedge funds and asset managers can connect to MTFs directly – becoming ‘members’ – while retail traders can only access the markets on offer via a provider of their choosing. MTFs are described as ‘multilateral’ because they have multiple members and users that are capable of interacting with each other to set prices.
