Abstract :
Summary form only given. We realised a InGaAs QW DBR laser with an electro-optical Bragg section using voltage to tune the wavelength. The tuning range is 25 Å for a 5 V drive voltage. And we measured on this device, the best switching time between the different accessible wavelength channels, ever reported on DBR laser: 600 ps, independently of the wavelength shift. These results demonstrate the capability of the EO-DBR laser for ultra-high fast optical switching operation
