Explore how PCB design for mechanical engineers is enabled through integrated ECAD-MCAD tools, improving product reliability and manufacturing efficiency.

In photonic integrated circuits, the light is subjected to losses such as insertion loss, branching loss, propagation attenuation, etc. For restoring power levels, optical amplification is a must. In  semiconductor optical amplifiers, the gain or amplification is achieved by injecting an electric carrier into the semiconductor to provide population inversion. The self-oscillation of the optical amplifier is prevented by eliminating the cavity reflection. Usually, antireflection coating and angle cleaving methods are employed to prevent self-oscillations. Semiconductor optical amplifiers are electrically pumped by injecting current.

The significance of PICs is growing as electronic ICs reach their maximum integration capacity. Under these circumstances, the potential of photonic integrated circuits is utilized in data communications, autonomous vehicles, aerospace aeronautical applications, etc.

Numerical Aperture (NA) is “… a critical value that indicates the light acceptance angle, which in turn determines the light gathering power, the resolving power, and depth of field of the objective.”(1) As light passes through a sample, the information describing the highest resolution information in the sample is diffracted at a very wide angle. Low magnification lenses typically have low NAs, meaning that they cannot capture the highest resolution information. To capture the widely diffracted information, high NA lenses move the front of the lens closer to the sample (increases the light acceptance angle). Dry lenses can only have NAs of up to 1.0. By using specially formulated oil and oil lenses, NAs of up to 1.4 can be achieved.

Light microscopes can, under the best conditions, resolve objects that are approximately equal to half the size of the wavelength used. In the real world this comes out to objects that are 250-300nm in size, if you are using a NA=1.4 objective lens (under optimal conditions). This means that you can make out two adjacent objects in this size range, assuming that you can see at least a 25% dip in intensity between them (Rayleigh criterion). Sample preparation is especially important when you want to resolve structures this small.

Semiconductor lasers generally consist of an amplifying medium placed inside a resonant cavity. The semiconductor laser is a common light source in photonic integrated circuits. In semiconductor lasers, the origin of the coherent optical emission is due to the stimulated transition from the higher energy conduction band to the lower energy volume band in semiconductors.

Photonic integrated circuits are classified into four groups based on their function, integration level, and substrate materials. The classifications are illustrated in the figure below.

Many of us have looked though the eyepiece of a department store microscope and seen a fuzzy looking “something” with the highest magnification objective lens. It’s not completely surprising that an inexpensive lens would give a blurry image. There are many optical aberrations that need to be corrected to manufacture the expensive lenses that are used on research grade microscopes.

Cutting-edge research is ongoing in photonic integrated circuit components to shrink their size for improved performance, functionality, and efficiency. Cadence software offers you an integrated electronic/photonic design automation (EPDA) environment where you can design photonic integrated circuits. The EPDA environment offers design, simulation, and analysis tools that help to manage complex designs and improve productivity with efficient photonics design workflows.

The “cost” of obtaining a higher NA is that the working distance (WD) of the lens becomes much shorter. Working distance is “… the distance between the objective front lens and the top of the cover glass when the specimen is in focus. In most instances, the working distance of an objective decreases as magnification increases.” (1) A smaller working distance can be a problem when you cannot see an object with a high magnification lens, even though you could see it with a low magnification lens. A 10x objective can have a WD of several millimeters (4-10mm, or 4000-10,000um). A well corrected, high NA 20x dry objective will have a WD of slightly less than 1mm (1000um). Most well corrected, high NA 40x and 60x oil objectives have working distances on the order of 0.1mm (100um).

Photonic integrated circuits (PIC) are chips containing photonic components that operate with photons. Light is injected into photonic integrated circuits to drive the components. All operations are controlled by light. Lasers are a common light source in photonic integrated circuits. Other components are used for the detection, manipulation, and amplification of photons.

With more electronics manufacturing capacity coming back to North America, electronics OEMs are considering friendshoring PCB production and product assembly.

Photonic integrated circuits are fabricated on standard semiconductors, compound semiconductors, nonlinear crystal materials, and dielectric materials. Some of the materials used in the fabrication of the photonic integrated circuits are:

John Burkhert shares his design experience and talks about the four biggest mistakes he's made during his career as a PCB designer, so that you can try and avoid them in your career as well.

High magnification without high NA does not give the resolving power that most people expect from a research grade microscope.  Using a high NA objective lens means that you are most likely sacrificing working distance (how deep into the sample that you can focus) for higher optical resolution. In most instances this is a very acceptable trade off.

In photonic integrated circuits, photons travel through optical components. Some photonic integrated circuit components are waveguides, polarizers, lasers, phase shifters, etc.

In photonics, photons are generated and utilized in a controlled environment. Among the kinds of radiant energies photons produce, photonic applications utilize the visible and infrared bands of the electromagnetic spectrum.
