Single axis fiber optic gyroscope FOG50A

The FOG 50A integrated photonic gyroscope is the first fully autonomous and groundbreaking closed-loop gyroscope with integrated optical devices and photonic crystal fiber rings. It adopts advanced material technology and chip technology, with characteristics such as high integration and high reliability.

Its main components are as follows:

1. Photonic crystal fiber ring: Circled by ultra-fine diameter and small bending radius photonic crystal fibers

2. Integrated optical devices: integrated SLD+MIOC (polarizer+coupler+Y-branch)+PD+TIA+TEC and other optical devices
