Abstract :
A three channel optical frequency locking was demonstrated using cascaded fibre Bragg gratings. The reflection wavelength of each grating is intentionally manipulated to ensure an unequal channel spacing. Three lasers were successfully locked to the transmission dips produced from the gratings. The frequency fluctuation was within 6 MHz, and the locking range appeared to be >15 GHz
