| Abstract: | Tunable semiconductor lasers are essential components for high|capacity wavelength|division|multiplexed (WDM) transmission systems and photonic switching systems in all|optical|networks of the present and next generations. They offer several opportunities to increase the capacity, functionality, and flexibility. Currently,devices capable of wide range continuous or quasi|continuous tuning have been fabricated using various advanced techniques, and several mature products have appeared on the market. In this paper are describe different kinds of tunable semiconductor lasers and their tuning mechanisms based on different resonator cavity structures, and discuss the advantages and disadvantages in their fabrication and application in optical communications. The latest progress in the development of semiconductor tunable lasers is summarized and some suggestions for their production in China are put forward. |
