Abstract
This thesis studies different avenues to miniaturize fiber-optic gyroscopes for navigation applications. In particular, a gyro was built using a 5.8-mm radius ring resonator on a chip with a quality factor of 100 million by using ultra-low-loss silicon-nitride waveguides. A record angular random walk per unit area was set for on-chip optical gyroscopes in the literature. Methods for enhancing the Sagnac phase were also studied, in particular by using exceptional points and loss compensation. Although operation at an exceptional point provides an enormous enhancement in the Sagnac frequency splitting, no enhancement was found in rotation sensitivity or precision. However, a very large enhancement in rotation sensitivity (a factor of 2400) was predicted in a coupled-ring gyro with gain, thereby showing great promise as a new architecture for which to build much smaller gyros.
