Dust Photonics is a silicon photonics company that has developed a product called Carmel. Carmel is a silicon photonics chip that is used for 400 gig and 800 gig applications.
It includes DustPhotonics’ special IP for attaching the laser onto a silicon photonics PIC which provides very low loss and very good performance. The Carmel chip is a cost-effective transmitter that converts electrical signals to optical signals using DustPhotonics’ Low Loss Laser Coupling (L3C technology).
DustPhotonics presented their evaluation board at ECOC 2022 in Switzerland. The system enables very good performance and also the lowest power that you can get in a transceiver. They demonstrated operation across different temperatures from room temperature to high temperature.
DustPhotonics has made a shift last year from being a transceiver company to being a silicon photonics component company. They are selling their products to transceiver companies and have a roadmap for next generation applications as well.
