Abstract
For the first time, a DBR laser has been integrated with a Mach Zehnde r intensity modulator in Er diffusion doped, Z cut LiNbO3, with Ti ind iffused waveguides and dry etched Bragg gratings. The monolithically i ntegrated device has a threshold of 54.8 mW incident pump power (lambd a p = 1480 nm) and emits, in a single longitudinal mode, up to 0.65 mW CW output power at hs = 1561 nm. The Mach-Zehnder type intensity modu lator has an optical bandwidth > 3 GHz.
