Abstract :
A novel two-dimensional (2-D) vertical-cavity surface-emission laser (VCSEL)-based wavelength converter was reported, in which the VCSEL was used both as the laser source for the probe wave and as the semiconductor amplifier for performing cross-gain modulation. We have developed a complete 2-D transmission line laser model to analyze the proposed structure. The optimization of the wavelength location, input power level, as well as the reflectivity of the VCSEL facet have been done with respect to the extinction ratio and peak chirp frequency.
