【摘要】 <正> A novel wideband digitally tunable laser based on fiber Bragg grating external cavities and 1×N opticalswitch provides 5 ms fast tuning time with output power more than 1 dBm over whole C-band that is onlylimited by the laser emission bandwidth. Less than 50 pm wavelength drift over-10 to 55℃ temperaturerange make that the wavelength locker and monitor are not necessary in this tunable laser.
