We demonstrate a novel compressed sensing Fourier-transform spectrometer (FTS) in a compact format. This FTS consists of 160 planar-waveguide Mach-Zehnder interferometers (MZIs) arrayed on a photonic chip, effecting a discrete Fourier-transform of th

A Custom-designed, digital sun sensor based on the orthogonal photodiode array is proposed. A well-known application of geometrical aperture mask on light detectors is utilized in a non-conventional design for CubeSat application. The main characteri

We develop a polarization characterization platform for optical devices in free-space quantum communications. We demonstrate an imaging polarimeter, which analyzes both incident polarization states and the angle of incidence, attached to a six-axis c

Secure optical communications networks are a functional requirement for many military, government, and civilian applications. Optical free space links provide security due to the small ground footprint of highly collimated laser beam patterns. Space-

90° hybrids are important components for coherent optical communications. Conventional implementations only cover the C band, while broadband, metamaterial-based devices require sub-100nm feature sizes. We propose a design based on dual-etch silicon

We develop a Silicon on Insulator based integrated optical chip for Interferometric Fiber Optic Gyroscopes. The optical design mirrors what is being done in literature, however some differentiating factors include: the introduction of a polarization
