Advances In The Opto-mechanical Design And Alignment Of The Hehsi Imaging Spectrometer Based On A Sagnac Interferometer
… Transform hyperspectral imager based on a Sagnac interferometer. This thesis research concentrates on the design upgrade and calibration of HEHSI from a proof of concept instrument to a prototype field instrument. Stability is enhanced by removing degrees of freedom and alignment is …

Nonreciprocal effects and their applications in fiber optic networks
… phenomena include the Faraday effect, Sagnac effect, Fresnel drag effect, nonlinearity or asymmetric geometric structure-induced nonreciprocity, and some pseudo nonreciprocity. The best-known application of nonreciprocity to optical components is the isolator, and the known …

High-quality source of fiber-coupled polarization-entangled photons at 1.56 [mu]m
… phosphate (PPKTP) crystal inside a polarization Sagnac interferometer at communication wavelength (1.56 [mu]m). A two-photon quantum interference visibility of 97.1% was measured. In addition to the Sagnac source, a linear Mach-Zehnder source at 810 nm was built for the Interdisciplinary Quantum …

Applications of single-photon two-qubit quantum logic to the quantum information science
… (PPKTP) crystal embedded in a polarization Sagnac interferometer and generation of hyper-entangled photon pairs that are simultaneously entangled in the polarization and momentum degrees of freedom. I also introduce deterministic quantum gates based on SPTQ quantum logic where the …

Ultrafast sources of entangled photons for quantum information processing
… photon source based on SPDC in a polarization Sagnac interferometer. We then studied the generation of coincident-frequency entangled photons for Heisenberg-limited quantum metrology. Using extended phase-matching conditions in a periodically-poled KTP crystal, generation of …

A multi-protocol quantum key distribution transmitter
… modulator is also developed, based on a Sagnac interferometer. This removes a side channel in QKD systems and integrates well with the directly-modulated quantum transmitter. This development also means that the transmitter can implement all current two-party QKD protocols based on weak …

Polarimetric Characterization Of Random Electromagnetic Beams And Applications
… Therefore, also based on a Mach-Zehnder interferometer, we proposed a new method for generating complex random electromagnetic beams. As a direct application of the cross-spectral density matrix formalism, it is shown that the spectral and the polarimetric characteristics of light can be …
