In this paper, we investigate the evolution of supercontinuum and femtosecond optical pulses generation through square lattice elliptical-core photonic crystal fiber (PCF) at 1550 nm by using both full-vector multipole method (M.P.M) and novel concrete algorithms: symmetric split-step Fourier (SSF) and fourth order Runge Kutta (RK4) which is an accurate method to solve the general nonlinear...

We present a novel direct space-to-time pulse shaper, operating in the 1.5m optical communications band which enables generation of continuous optical pulse sequences at a rate of 100GHz. The apparatus includes several novel features, such as the use of a diffractive optical element for spatial patterning, fiber coupled input/output, and a telescopic configuration which collectively enable gene...
We describe a method of ultrashort-pulse and ultrafast-pulse-train generation through optical parametric amplification of a laser beat wave. Numerical simulation shows that 250-fs laser pulses at 1.55 lm are generated from a beat-wave seeded optical parametric amplifier pumped by a 30-ps laser at 1064 nm. The pulse compression is attributable to sideband generation and parametric amplification ...
We present our work in optical generation of arbitrarily shaped millimeter-wave electromagnetic waveforms. Through a novel technique, which utilizes tailored optical pulse sequences from a direct space-to-time pulse shaper to drive a high-speed optical-to-electrical converter, we generate amplitude-equalized, arbitrarily phaseand frequency-modulated waveforms at center frequencies approaching 5...
We demonstrate an all-optical technique for the elimination of timing jitter in short pulse transmission systems. The technique relies on pulse pre-shaping followed by optical switching in a periodically poled lithium niobate waveguide via cascaded second harmonic and difference frequency generation. ©2010 Optical Society of America OCIS codes: (060.2330) Fiber optics communications; (130.3730)...
ulse-shaping techniques, in which user-specified ulrashort pulse fields are synthesized via parallel manipuation of optical Fourier components, are now widely dopted [1]. Among the almost arbitrary waveforms enbled by pulse shaping, one subset with particular appeal nvolves generation and manipulation of optical pulse rains. Discrete pulse train packets (or bursts) have been enerated by both Fo...
