Abstract

We have developed a quantum dash (QDs) mode locked laser (MLL) using an asymmetrical cladding for high frequencies microwave generation. The laser exhibits more than 400 mW output power. The optical comb is 9.2 nm wide with 10 GHz free spectral range. Thanks to optical compression we have increased the signal to noise ratio by 25 dB. The MLL can be locked on an external source. We have demonstrated RF lines from 10 to 120 GHz with 10 GHz spacing.
