While silicon photonics is an attractive platform for neuromorphic computing, it generally lacks scalable nodes that provide nonlinearity and memory. Here, the authors show experimentally that simple and compact networks of silicon microring resonators exhibit complex self-pulsing responses that can be exploited for all-optical long-term memory and sensing.

UV filtering acrylic is one of the most popular specialized acrylic sheeting solutions on the market today. Although UV filtering plexiglass can not completely prevent colors from fading or darkening, it does filter out up to 98% of harmful UV light. This makes it the ideal plastic sheet material for protecting artwork, paper, or other keepsakes, that can turn yellow, fade, and become brittle.   It’s important to know that not all UV filtering plexiglass sheets are created equally, as some block more UV rays than others, and some even filter out harmful visible light rays. The UV protection of this acrylic sheeting only blocks UV wavelengths shorter than 400 nanometers. Visible light can also be harmful, especially in the lower violet range from 400-500 nanometers, and is blocked by certain kinds of UV filtering sheeting such as UF3 acrylic and museum grade acrylic.

Although UV filtering acrylic is more popular than UV transmitting and has more applications, UV transmitting acrylic is important in places where the UV rays are required. With impeccable clarity, excellent weatherability, and high light transmission, this plastic has no additives to block the transmission of UV light. While UV filtering acrylic blocks up to 98% of UV rays, UV transmitting acrylic allows up to  92% UV ray transmission.

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and interference, and also studying the quantum mechanical properties of individual packets of lights known as photons.

The authors investigate spin-valley polarization in hybrid systems of Au nanoparticles and monolayer MoS2 and observe a nearly complete quenching of the far-field circular polarization state of emission from MoS2 at the position of the nanoparticle. This highlights the need to consider an ensemble, rather than just a single rotating dipole emitter, for precise predictions of polarization responses in these hybrid systems.

Optical waveguides that route light are a core technology of modern photonics and the bedrock of the global communications network. A surprising diffusion mechanism for guiding light has now been identified, and it is strangely close to home.

Imaging in the water window has traditionally relied on large synchrotron radiation sources. Now, a tabletop tunable X-ray source which generates water-window X-ray photons from a low energy electron beam interacting with a van der Waals crystal has been demonstrated.

Although the most common application of UV filtering acrylic plastic is for framing, this plexiglass is warranted for a variety of projects including:

We propose a multi-particle ‘which-path’ gedanken experiment with a quantum detector. Contrary to conventional ‘which-path’ experiments, the detector maintains its quantum state during interactions with the particles. We show how such interactions can create an interference pattern that vanishes on average, as in conventional ‘which-path’ schemes, but contains hidden many-body quantum correlations. Measuring the state of the quantum detector projects the joint-particle wavefunction into highly entangled states, such as GHZ’s. Conversely, measuring the particles projects the detector wavefunction into desired states, such as Schrodinger-cat or GKP states for a harmonic-oscillator detector, e.g., a photonic cavity. Our work thus opens a new path to the creation and exploration of many-body quantum correlations in systems not often associated with these phenomena, such as atoms in waveguide QED and free electrons in transmission electron microscopy.

Divacancy color centers in SiC are promising candidates for a spin-photon interface, but typically show charge-state instability under optical excitation. Here the authors show that modified divacancies created by a focused helium ion beam are robust against photoionization and have promising properties.

Plastic sheeting with unique UV characteristics is often used where UV rays are an issue, whether it is UV filtering or transmitting. Applications that commonly see problems with traditional acrylic sheeting include display cases, museum lighting, animal habitats, tanning beds, and more. UV filtering acrylic sheet is used when UV light is not desired, and UV transmitting acrylic is used when UV light is required.

One of the most common applications of UV transmitting plexiglass is indoor tanning beds. In order to effectively tan skin, UV rays have to be absorbed by the skin. Traditional plexiglass does not allow enough UV rays through, although it is more than UV filtering plexiglass does. Other applications include:

Current optical skyrmion generators involve complex bulky systems, hindering further practical applications. We propose an integrated metafiber for high-quality photonic skyrmions, with subwavelength polarization features and topology tunability.

UV Transmitting acrylic sheeting was designed specifically for indoor tanning applications as its properties allow for high UV light transmission, while retaining structural stability.

Greenhouses are the second most common application of UV transmitting acrylic sheeting as plants see better growth due to high light transmission.   There are some things that both UV transmitting and UV filtering acrylic have in common:
