ASE Light Source for Fiber optic gyro

The ASE light sources base on the technology to utilize doped fiber to produce the amplified spontaneous emission. FOG photonics offers a full range of industry leading ASE light sources, which integrate ATC (Automatic Temperature Control) and APC (Automatic Temperature Control) circuits inorder to accurately constraint temperature and power variation. Thus, they could exhibit excellent performance, including spectral and power stability and be suitable for high-precision fiber optic gyroscope (FOG).
