Abstract
Edge-emitting 1.55- platelet InGaAs/InP laser diodes are bonded in 6.5--deep recesses etched into a thick layer on an Si substrate so that they are aligned and coaxially coupled to SiON dielectric waveguides fabricated within the layer. The integrated lasers show room temperature pulsed and continuous wave (CW) lasing at threshold currents of 17 and 19 mA, respectively. The CW output power measured from the end of the dielectric waveguide at the edge of the chip is more than 1 mW, and laser-to-waveguide coupling losses under 2 dB are observed. CW spectral measurements show single-mode emission in the vicinity of 150 . The integrated structure is highly planar with a footprint of only 150 300 , and the integration process is modular and can be used to integrate a variety of devices on the same substrate.Keywords
