On-Chip Group-IV Heisenberg-Limited Sagnac Interferometric Gyroscope at Room Temperature by Francesco De Leonardis, Richard Soref, Martino De Carlo, Vittorio M. N. Passaro

“…The chip comprises several beam splitters, two SFWM entangled photon sources, a pump filter, integrated Mach–Zehnder interferometric gyro, and an array of waveguide coupled GeSn/Ge/Si single-photon avalanche detectors. The laser pumped SWFM sources generate the signal-idler pairs, which, in turn, are used to measure the two-photon, four-photon, and higher order coincidences, resulting in an increasing of the gyro resolution by a factor of two and four, with respect to the classical approach.…”

Incident Angle Dependence of the Waveform of the Polarization-Sensitive Photoresponse in CuSe/Se Thin Film by Arseniy E. Fateev, Tatyana N. Mogileva, Vladimir Ya. Kogai, Konstantin G. Mikheev, Gennady M. Mikheev

“…It has been established that the durations of unipolar longitudinal photocurrent pulses at linear and circular polarizations of laser pumping do not depend on the angle α. It is shown that the evolution of the temporal profile of the helicity-sensitive transverse photocurrent with a change in α strongly depends on polarization. …”
