PHYSICAL SCIENCES INC. SBIR Phase I Award, June 2023

Interferometric fiber-optic gyroscopes (IFOGs) are a key component within an inertial navigation system, however, current IFOG systems are limited by the unnecessarily large size, weight, and power (SWaP) of the integrated optical chip. To overcome the current limitations, Physical Sciences, Inc. (PSI) will develop Integrated Lithium Niobate chips for Gyroscope Support (I-LiNGS) to enable highly compact, ultra-low drive-voltage (V-p) electro-optic modulators in support of next generation low SWaP IFOGs. To produce the lowest SWaP system PSI will leverage thin-film lithium-niobate (TFLN) that can be scalably manufactured using a commercial wafer-scale production capability. ???????
