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

Abstract
For the first time, a DBR laser has been integrated with a Mach Zehnder intensity modulator in Er diffusion doped, Z cut LiNbO,, with Ti indiffused waveguides and dry etched Bragg gratings. The monolithically integrated device has a threshold of 54.8mW incident pump power (hp = 1480nm) and emits, in a single longitudinal mode, up to 0.65 mW CW output power at hs = 1561nm. The Mach-Zehnder type intensity modulator has an optical bandwidth > 3GHz.File in questo prodotto:
