In this paper,a novel monolithically integrated two-port optical transceiver for FTTH is studied,its direct modulation response with relation to its structure and performances analyzed,and its relaxation oscillation,gain suppression and frequency chirp calculated.

It is discussed the influence of nonlinear frequency chirp to the transmission of 2nd-soliton in optical fibers by solving nonlinear Schrdinger equation.

The effect of the linear frequency chirp on the supercontinuum spectrum generation of Gaussian input pusle is numerically investigated in the anomalous dispersion-flatted fiber with convex dispersion profile by the split-step Fourier method.

Starting from the extended coupled nonlinear Schrdinger equations including quintic nonlinearity,the expressions for the nonlinear phase shifts and frequency chirps of different pulse pairs were derived,and the phase shifts,chirps and power spectra of pulse pairs with different shapes were simulated,compared and analyzed.

Utilizing the cubic-quintic nonlinear Schrdinger equation in which the dispersion of optical fibers is neglected,the nonlinear phase shifts and frequency chirps of super-Gaussian optical pulses are calculated and investigated analytically.

The purpose of the paper is to study the synthetic effects of the negative quintic nonlinearity of optical fibers and the initial frequency chirps of optical pulses on the frequency chirps and spectra of Gaussian optical pulses.
