$239,958Benefit:
The DoD applications of our proposed design include interferometric fiber optic gyroscopes (IFOGs) and accelerometers for use in strategic-grade high precision inertial sensors. For this application, the inherent wide optical bandwidth and spectral symmetry of superluminescent diodes (SLDs) are highly advantageous compared to the narrow and asymmetric spectral bandwidth of traditional laser diodes. However, the relatively low available output power of present SLD technology restricts the performance and package size of IFOGs, limiting their deployability in the field. Our proposed approach will enable an order-of-magnitude increase in SLD power compared to the present state of the art. This will allow miniaturization of the IFOG system sense coils which will ultimately lead to improved performance and reduction in system SWaP-C. Our device architecture is also ideally suited for dual-use applications in optical coherence tomography.
