The latest photonic integrated circuit products for 2022

A look at the market for photonic integrated circuits and some of the products and solutions available

A photonic integrated circuit (PIC) is a device that can integrate multiple photonic components such as interconnect waveguides and optical amplifiers, to form one photonic circuit. 

PICs are similar to electronic integrated circuits, with the main difference being that PICs can perform functions for information signals imposed on optical wavelengths typically in the visible spectrum or near infrared 850 to 1,650nm

Like electronic integrated circuits, they are fabricated in foundries using photolithography to pattern wafers for etching and material deposition. PICs are used in a wide range of applications, thanks to their small size and robust nature. These include: high-speed data transmission for the telecoms and datacoms sectors; optical sensing for the environment, medicine and life sciences; various imaging and scanning systems for civil security and industry; and lidar systems in the automotive sector.

The first transmitter PIC was the electroabsorption-modulated laser (EML), which was developed in 1987. Today, this cost-effective photonic hardware is also seeing high demand in applications such as data centres, according to the latest data from research firm,

The company said that the global PIC market was valued at $5,790m in 2020, and predicted that it will be worth $21,649m by 2026, registering a compound annual growth rate of 22.4 per cent during the forecast period of 2021 to 2026.

VLC Photonics: Featured photonic integrated circuits product

VLC Photonics offers worldwide independent testing services for both vertical and edge emitting photonic integrated circuits (PICs) at wafer level. Photonic integration is gaining momentum and more people are looking at developing PICs for many applications, including optical transceivers, LiDAR, quantum and sensing among others.

As PICs are not as mature as electronic circuits, it is still critical to do extensive characterisation and testing for validating PIC designs towards production. To this aim, wafer level testing is strongly needed, and needs to be compatible to both vertical and edge emitting types of PICs.

With the new VLC Photonics Wafer level testing services, companies can close design loop from fabricated to measured devices with massive data, allowing for statistical parameter modelling. Moreover, these massive data provide feedback for fab yield improvement, to accelerate product development and volume ramp up, as well as automate the identification of known good dies (KGDs) to sort dies wafers in production, and towards packaging.
