Abstract :
For the first time, a DBR laser with an electro-optical Bragg section is reported for fast wavelength tuning operation. Using voltage to tune the wavelength, we measured on this device, the shortest switching time between different wavelength channels ever reported on DBR lasers: 500 ps, independently of the wavelength shift.<>
