Radio over fiber (RoF) is a promising technique in providing broadband wireless access services in the emerging optical-wireless networks. Optical millimeter-wave (mm-wave) generation is a key technique to realize low cost and high transmission performance in the RoF systems. Several techniques have been proposed for the optical generation of mm-waves such as direct modulation, external modulation,...
Phase-coded optical signal was spectrally translated from the conventional near-infrared communication band to the visible band. Spectrally narrow 780-nm pump was combined with phase-modulated 1575-nm signal in a small core photonic crystal fiber (PCF), to generate 518-nm idler through parametric process. The phase-modulated idler carrying 1-Gbps information was received in an error-free manner. The...
Slow- and fast-light is the control of the velocity of light in a medium by light. As a fascinating new field in physics there is a fundamental interest on this effect on the one side, but on the other side there exist a lot of practical applications for telecommunication and information systems. Among these are optical signal processing, the radio frequency-photonics, nonlinear optics and spectroscopy...
We propose the use the recently discovered effect of spectral self-phase conjugation in SBS for coherent beam combining of the output from an array of high power fiber amplifiers.
