We propose a bidirectional Radio-over-Fiber (RoF) system with multi-band signals generation technique using a single phase modulator (PM). At central office (CO), a PM is used to modulate optical carrier and generated signal is transmitted through a single mode fiber (SMF). At base station (BS), three different signals are generated from the received optical signal, including 60 GHz millimeter ...

Recent advances in coherent optical receivers is reviewed. Digital-Signal-Processing (DSP) based phase and polarization management techniques make coherent detection robust and feasible. With coherent detection, the complex field of the received optical signal is fully recovered, allowing compensation of linear and nonlinear optical impairments including chromatic dispersion (CD) and polarizati...

This paper presents a technique for multi-channel optical ow estimation. We combine the brightness constancy constraint with the relationship between optical ow elds and disparity elds in estimating optical ow elds by solving systems of linear equations. In this formulation, the so called round-about compatibility constraint is used to ensure the coherence between optical ow elds and to pin dow...

We demonstrate numerically that partially incoherent light can be trapped in the spectral band gaps of a photonic lattice, creating partially incoherent multi-component spatial optical solitons in a self-defocusing nonlinear periodic medium. We find numerically such incoherent multi-gap optical solitons and discuss how to generate them in experiment by interfering incoherent light beams at the ...

The goal of the research reported here was the development of a circuitbased modeling procedure for both the passive and active components of a quasi-optical power combiner. Contributions include the development of a multi-port equivalent circuit of a multi-element quasi-optical power combiner. Excellent agreement with experimental results was obtained. Mount independent techniques "were also d...
