Abstract

The rapid advancement in integrated optics offers a viable approach for further reducing the size and weight of interferometric fiber optic gyroscopes (IFOGs) by integrating optoelectronic transceiver modules. This paper proposes a design for an integrated optoelectronic transceiver module for IFOG, incorporating a superluminescent laser diode (SLD) light source, beam splitter, photodetector (PD), and transimpedance amplifier (TIA). Through optimization of the optical path and structural design, the emitted optical power from the fiber pigtail exceeded 1 mW under a 100 mA drive current, with the closed-loop overall loss measured at approximately 13 dB. An integrated IFOG test system was developed, and its zero-bias stability was measured at 0.3755 °/h, meeting the requirements of tactical-grade systems. The transceiver shows substantial potential to streamline the IFOG assembly process and reduce assembly costs, a critical factor in the miniaturization of IFOGs.
