Anello photonic is a silicon valley based startup developing next generation navigation technologies. The heart of the Anello’s products is the silicon photonics optical gyro, the SiPhOG™ which is a 10X reduction in SWAP-C compared to current products. Over the past years ANELLO partnered with a high volume fab in the US to build state of the art silicon nitride process technology. ANELLO’s SiN process technology made new optical device possible. In this presentation we will provide an overview of how ANELLO siliconized the Gyro and some of the key achievement of ANELLO silicon nitride capabilities and devices.
