We have developed a new generation of inertial measurement units (IMUs) that are based on 3-axis closed-loop fiber optic gyroscopes (FOGs) operated by a highly integrated SLED transceiver optical module, thereby eliminating several discrete optical components like depolarizers, fiber couplers or fiber-pigtailed photodiodes. Removing many fiber components lowers system costs but also reduces the nu...Show More
An optical transceiver module, based on a broadband Superluminescent Light-Emitting Diode (SLED) at 1550 nm and an integrated receiver photodiode, has been developed. The compact 14-pin butterfly (BTF) module integrates micro-optical lenses, a flatpack optical isolator, a 50:50 beam splitter and other components on a temperature-controlled, free-space optical bench platform and is delivering, at a...Show More
A novel, 14-pin Butterfly (BTF) light source module, incorporating a broadband Superluminescent Light-Emitting Diode (SLED) at 1550 nm, has been developed for inertial measurement unit (IMU) applications. The compact BTF module integrates micro-optical lenses, a flatpack optical isolator, a monolithic 1:3 beam divider and other components on a temperature-controlled, free-space optical bench platf...Show More
