O-band DFB laser heterogeneously integrated on a bulk-silicon platform

An O-band DFB laser heterogeneously integrated on bulk-silicon platform is presented. A high wall plug efficiency of over 8% up to 70°C is achieved due to efficient heat dissipation from III/V active region to silicon platform. The single-mode operation is maintained in a wide current range with sid...

Zusammenfassung:An O-band DFB laser heterogeneously integrated on bulk-silicon platform is presented. A high wall plug efficiency of over 8% up to 70°C is achieved due to efficient heat dissipation from III/V active region to silicon platform. The single-mode operation is maintained in a wide current range with side-mode suppression ratio over 45dB. This result completes the optical device library suite for the bulk-silicon platform used in most semiconductor products.
