Differentialities between integrated photonic circuits, such as silicon photonics, optical units and

What makes photonic integrated circuit distinct from optical circuit? Well compare it to an optical component that incorporates several optical elements..

Photonic integrated circuits may be less hefty than optical units..

Within an optical module, the manufacturer fixates the individual optical components to the arranged and assembled housings, whereas the engineers may integrate the photonic integrated circuit onto a single chip, which makes it smaller.

The photonic circuits are able to work with less power than optical units..

In contrast to an optical device that operates with optical elements arranged in an enclosure, the design of photonic integrated circuits combines micro optical elements, allowing them to function at low energy levels.

it makes benefit of the optical confinement of the photonic crystal that makes the circuit smaller and uses less energy for optical..

About VLC, the company that contributed to the writing of this article..

Completely assist customers in the realization of photonic integrated circuits from both technical and business perspectives..

The Technical University of Valencia, Spain, created the company, and VLC manufactures fabless silicon photonics, as well as various other integrated circuits based on photonics.

In the year 2011, Jose Capmany, a professor at the school, and Pasqual Munoz, an assistant professor at the university, established VLC. VLC members possess high end of academic experience, and aid customers in the creation of Photonic integrated circuits..

Help from the business perspective as well as from the technical aspect

VLC can comprehend the details of different industry trends as well as the standards they set, and can evaluate the specifications needed and the price associated with photonic integrated circuits.. Additionally, they are able to estimate the costs beginning from R&D through the stage of mass production and allows VLC to analyze and evaluate technological and business factors..

Researchers can develop photonic integrated circuits using more than silicon but also various compounds of semiconductors.

Alongside designing using silicon photonics, engineers can also use VLC for creating with other semiconductor compounds including InP (indium phosphide) as well as GaAs (gallium arsenide).

In the near future, many different applications are likely to use the technology of photonic integration, although in some instances the silicon may not be able to meet the specifications.

we hear that companies who design photonic integrated circuits usually use silicon as the primary material that they will use, for instance..

VLC they have years of experience researching and vast knowledge regarding not just silicon but also other semiconductor components, which means they are able to present broad array of solutions to better satisfy the needs of customers..

Also tested by fabricating electronic photonic circuits..

point no1:

The majority of other companies that are not fabless do just designing; however, VLC will evaluate the effectiveness of PIC when it manufactures and designs. After the fabrication process is complete, the team will test the characteristics of the circuit.

If the circuit doesn’t meet the standards, they will suggest improvements to support the prototyping process through manufacturing, design, and packaging. VLC equips itself with semiconductors that power the chips, measuring components including optical probes, as well as test equipment.

point no2:

As result, whenever client requests testing, the company will react immediately.. Furthermore, VLC can test equipment not just at the chip level, but also at the level of the wafer, significantly reducing the amount of time needed for inspection. One of the major challenges to the practicalization and mass production of silicon photonics is the fact that theres huge gaps between simulation results in the design phase and performance following actual packaging.. VLC has set out to address this issue by building up in house experience in characterization as well as details on results of evaluation.. Have wide foundries networks

As VLC develops photonic integrated circuits that comprise several silicon series and compound, they excel at picking foundries, and working with them based on their materials of base.. For the packaging of PIC They also have agreements with different packaging firms and can offer packaging solutions that will meet the customers demands..

point no3:

Although they may be able to design the photonic integrated circuit, they have to consider manufacturing aspects like whether they can make the circuit and what the yield will be.

In collaboration with numerous foundries VLC gained experience that allows them to develop high yielding products in accordance with the products and foundrys features.. Thus, VLC is able to select and recommend the most suitable foundry to meet the clients preferred design..
