Scintil, Tower Semiconductor Poised to Boost PIC Production

Photonic integrated circuits (PICs) supplier Scintil Photonics has integrated III-V distributed feedback (DFB) lasers and amplifiers with standard silicon photonics technology in production at Tower Semiconductor. The integration technology grants opportunities to accommodate the integration of additional materials and functions, including lithium niobate and quantum dots, said Sylvie Menezo, president and CEO of Scintil Photonics.

Scintil unveiled its fully chip-integrated 100-GHz DFB comb laser source offering in March 2023. The company said that its continued partnership with Tower positions it for high-volume production to meet market demand.

Scintil’s integrated circuits (ICs) are made using a combination involving standard silicon photonics processes, flip bonding, and standard CMOS processes to enable monolithic integration of lasers and amplifiers that target improved performance, speed, reliability, and high-density at lower power consumption for data center, AI, and 5G applications. Fabricated on Tower’s high-volume base, PH18M silicon photonics foundry technology, which includes low-loss waveguides, photodetectors and modulators, Scintil’s technology monolithically integrates DFB lasers and amplifiers on the backside of wafers. Further testing of Scintil’s circuits by customers showed no need for a hermetic package, while demonstrating improved aging and robustness, the company said.

Glossary

photodetector: A photodetector, also known as a photosensor or photodiode, is a device that detects and converts light into an electrical signal. Photodetectors are widely used in various applications, ranging from simple light sensing to more complex tasks such as imaging and communication. Key features and principles of photodetectors include: Light sensing: The primary function of a photodetector is to sense or detect light. When photons (particles of light) strike the active area of the photodetector,...
integrated photonics: Integrated photonics is a field of study and technology that involves the integration of optical components, such as lasers, modulators, detectors, and waveguides, on a single chip or substrate. The goal of integrated photonics is to miniaturize and consolidate optical elements in a manner similar to the integration of electronic components on a microchip in traditional integrated circuits. Key aspects of integrated photonics include: Miniaturization: Integrated photonics aims to reduce the...
