摘要: Record low optical threshold power and high slope efficiency are reported for arrays of distributed Bragg reflector lasers integrated within an ultra-low-loss Si(3)N(4) planar waveguide platform. Additionally, feedback laser designs presented that show improvements in pump-to-signal conversion over two orders magnitude beyond found previously published devices. Lithographically defined sidewall gratings provide the required lasing both cavity configurations. Lasing emission is shown a wide wavelength range (1534 to 1570 nm), with output powers up 2.1 mW side mode suppression ratios excess 50 dB.
