We investigate the torque on a specially shaped rotator produced by a vortex beam. The formulas for the torque alongx, yandzdirections are derived, and numerically calculation is performed. It is foun...
In a nano-ridge waveguide under oblique illumination, we demonstrated transmission enhancement resulting from a hybrid effect between propagation modes and surface plasmon wave. The measured near-fiel...
Semiconductor avalanche photodiodes (APDs) are commonly used for single photon detection in quantum key distribution. Recently, many attacks using bright illumination have been proposed to manipulate ...
Birefringence property of E7 nematic liquid crystal is investigated via voltage dependent transmittance spectrums. Measurements are performed at wavelength 632.8 nm, which is the absorbance peak of ou...
The effect of pre-illumination on both thermally stimulated current and photocurrent spectra of TlInS2 crystal is investigated. The increase in the photosensitivity of the crystal by several orders of...
