EVALUATION METHOD FOR PARASITIC EFFECTS OF THE ELECTRO-OPTICAL MODULATOR IN A FIBER OPTIC GYROSCOPE [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2016 Subject of Research.The paper proposes an original method for studying the parasitic effects in the electro-optic modulator of the fiber optic gyroscope. Proposed method is based on the usage of a special waveform phase modulation signal. Method.

Effects of self-phase modulation on weak nonlinear optical quantum gates
, 2007 A possible two-qubit gate for optical quantum computing is the parity gate based on the weak Kerr effect. Two photonic qubits modulate the phase of a coherent state, and a quadrature measurement of the coherent state reveals the parity of the two qubits ...

Spectroscopy for cold atom gases in periodically phase-modulated optical lattices [PDF]
, 2011 The response of cold atom gases to small periodic phase modulation of an optical lattice is discussed. For bosonic gases, the energy absorption rate is given, within linear response theory, by imaginary part of the current correlation function.

Measuring the Reflection Matrix of a Rough Surface
Applied Sciences, 2017 Phase modulation methods for imaging around corners with reflectively scattered light required illumination of the occluded scene with a light source either in the scene or with direct line of sight to the scene. The RM (reflection matrix) allows control

Performance Optimization of SNR and SFDR in RoF Link for the Next Generation Networks
The Journal of EngineeringA radio frequency over fibre (RFoF) or radio over fibre is a versatile technology, in which light is modulated with radio frequency signal and an optical fibre link is used as a medium to transmit it.

Rotating vortex imaging implemented by a quantized spiral phase modulation [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 We demonstrate both theoretically and experimentally that a spiral mask with a finite number of discrete phase levels allows a defocusing induced rotation of the point spread function in the vortex imaging.
