We demonstrated fast optical power control and wavelength switching in a tunable SOA-integrated SGDBR laser. With our design, output power of the laser can be precisely controlled within 0.1 dB and rapidly shuttered within 2 ns.
This letter demonstrates a fast optical wavelength-tunable transmitter based on a sampled grating distributed Bragg reflector (SG-DBR) laser. A high-precision clock distributing circuit has been introduced into the transmitter to guarantee the switching synchronization for driving currents to different tuning sections of the SG-DBR laser. To achieve fast and accurate wavelength switching, a linear...
