Monolithic integration of laser and waveguide using a twin-guide structure with absorption layer

We demonstrate for the first time the use of absorption layer to achieve mode control in an InP/InGaAsP integrated twin-guide (TG) laser structure. The In/sub 0.53/Ga/sub 0.47/As layer eliminates the even mode and makes characteristics of the integrated device insensitive to laser cavity length and...

Zusammenfassung:We demonstrate for the first time the use of absorption layer to achieve mode control in an InP/InGaAsP integrated twin-guide (TG) laser structure. The In/sub 0.53/Ga/sub 0.47/As layer eliminates the even mode and makes characteristics of the integrated device insensitive to laser cavity length and structure variations, without degrading performance. A record high coupling efficiency of 45% from the TG laser to the integrated passive waveguide is obtained.
