2mW 1310nm SLED Superluminescence diode laser for fiber optic gyroscope

A key application for SLED is in navigation systems, such as those in avionics, aerospace, sea, terrestrial, and subsurface, that use fiber-optic gyroscopes (FOGs) to make precise rotation measurements. FOGs measure the Sagnac phase shift of optical radiation propagating along a fiber-optic coil when it rotates around the winding axis. When a FOG is mounted within a navigation system, it tracks changes in orientation.
The basic components of a FOG, are a light source, a single-mode fiber coil (could be polarization-maintaining), a coupler, a modulator, and a detector. Light from the source is injected into the fiber in counter-propagating directions using the optical coupler.
