We report the InAs/GaAs quantum dot laterally coupled distributed feedback (LC-DFB) lasers operating at room temperature in wavelength range of 1.31 µm. First-order chromium Bragg gratings were fabricated alongside ridge waveguide to obtain maximum coupling coefficient with optical field. Stable continuous-wave single-frequency operation has been achieved output power above 5 mW/facet and side ...

We demonstrate an array of erbium-doped waveguide-distributed feedback lasers on an ultra-low-loss Si(3)N(4) platform. Sidewall gratings providing the lasing feedback are defined in the silicon-nitride layer using 248 nm stepper lithography, while the gain is provided by a reactive co-sputtered erbium-doped aluminum-oxide layer. We observe lasing output over a 12 nm wavelength range (1531-1543 ...

On chip, high power (75mW), erbium-doped distributed feedback lasers are demonstrated in a CMOS compatible fabrication flow. The laser cavities consist of silicon nitride waveguide and grating features defined by wafer-scale immersion lithography and a top erbiumdoped aluminum oxide layer deposited as the final step in the fabrication process. 2013 Optical Society of America OCIS codes: (130.0...
