Abstract :
Wavelength switching of four wavelengths spanning 5.1 nm was realized by gain switching and self-seeding of a commercial Fabry-Perot (F-P) laser diode with a single in-fiber linearly chirped Bragg grating as the external cavity. A driving frequency up to 2 GHz was used and single mode operation with a side mode suppression ratio of 10 dB overall and 25 dB at best was achieved.
