Paper Abstract

We propose a new method to investigate fast wavelength switching, which consists of control circuit, driving circuit and 8-channel DFB laser array using reconstruction-equivalent-chirp technique. The control circuit is in charge of selecting required lasers to switch wavelength, the driving circuit supply adjustable and stable direct current to the DFB laser arrays. Experimental results show that wavelength switching time of 8 channels is about 500ns and stability of laser output is promised.
