Abstract :
Selective MOVPE growth is used to develop multiwavelength MQW-DBR lasers. Selectively grown waveguide layer thicknesses in the DBR region are varied by controlling the mask stripe width, resulting in wavelength control in MQW-DBR laser arrays fabricated with a constant period grating. A wavelength span of over 20 nm at a 2.5 nm constant wavelength step is demonstrated for 10 consecutive lasers
