Lead selenide and lead selenide/lead sulfide core/shell nanocrystals were investigated for use in near infrared photodetectors. A colloidal synthesis method was used for both the core and core/shell configurations. The lead sulfide shell was examined in order to mitigate oxidation of the nanoparticle surface. Absorbance and photoluminescence spectra were measured at room temperature and 77 K, respectively. Transmission electron microscopy images were also obtained to confirm crystallography and size. Bulk lead selenide was simulated in WIEN2k utilizing the linear-augmented plane wave method of solving density functional theory to better understand the electronic structure of PbSe. The crystal structure, electron density, band structure and density of states are presented and discussed. The calculations correctly predicted a direct band gap at the L point in the Brillouin zone. The band gap calculated was 0.40 eV.

Despite the success of the fiber-optic gyroscope as the world's most commercially successful fiber sensor, improving fiber-optic gyroscope (FOG) technology, particularly with regards to temperature stability, is increasingly important. Commercial FOGs have been able to meet these requirements through extensive engineering, including temperature modeling and control to reduce the drift caused by temperature-gradient variations in the sensing coil (the Shupe effect) and mu-metal shielding to reduce the drift caused by exposure to varying magnetic fields coupled to the Faraday effect. The use of a hollow-core fiber (HCF) in a fiber-optic gyroscope offers an attractive way to ease these and possibly other engineering requirements because in an HCF light travels mostly in air, where these two effects are greatly reduced. We propose and test the first implementation of a polarization-maintaining HC FOG. The HCF coil ends are directly attached to the multi-function integrated optics LiNbO3 chip, overcoming what has long been one of the biggest challenges in implementing a hollow-core fiber in this sensor. To fully characterize this FOG it was interrogated, in turn, by a broadband supersluorescent fiber source (SFS), a laser, and a laser broadened with Gaussian white noise. The SFS-driven HC FOG has a measured rotation-rate resolution comparable to that of a commercial FOG utilizing a solid-core fiber, and 3.4 times lower measured drift than previously reported for a hollow-core FOG. With a longer coil or a larger coil diameter, these values could approach the requirements for aircraft navigation. A theoretical model of optimal phase biasing was developed to further improve these results. This thesis will show that the noise of the broadened-laser-driven HC FOG is then dominated by a new effect, which is scattering mediated by coupling to the highly scattering surface modes of the HCF. Previous models of the backscattering drift in FOGs had uncertain convergence for broad source linewidths due to computation requirements. We present a new model of backscattering drift that solves the previous convergence issues by introducing a coherence function. This model was important for identifying the source of drift in the HCF FOG driven by light sources of various linewidths, and it was used to verify the backscattering coefficient for the HCF and confirm the existence of highly scattering surface modes.
