In most applications of vertical-cavity surface-emitting diode lasers (VCSELs), their stable and efficient single-mode operation is required. In standard VCSEL designs, single-longitudinal-mode operation is assured because of their short optical cavities. There is, however, a real problem, how to reach single damental-transverse-mode (SFM) operation, especially in modern intra-cavity contacted VCSELs...
Three methods to obtain in GaAs-based oxide-confined GaInNAs/GaAs quantum-well (QW) VCSELs an efficient emission of the 1.3-mum radiation have been analysed and compared with the aid of the comprehensive fully self-consistent model. In the tuned VCSEL, QW composition (high N content) and thickness are selected to tune the 1.3-mum emission which ensures low threshold currents. However, manufacturing...
In this paper, the comparative analysis of the room-temperature (RT) continuous-wave (CW) threshold operation of index- (IG) and gain-guided (GG) oxide-confined (OC) vertical-cavity surface-emitting diode lasers (VCSELs) is carried out with the aid of the comprehensive fully self-consistent optical-electrical-thermal-recombination simulation model. As expected, performance of IG and GG OC VCSELs is...
In the paper, the comparative analysis of the room-temperature (RT) continuous-wave (CW) threshold operation of various designs of oxide-confined VCSELs is carried out using the standard 1.3-mum intracavity-contacted oxide-confined GaAs-based quantum-well (GaIn)(NAs)/GaAs VCSEL as a typical example. The comparison is performed with the aid of the comprehensive fully self-consistent optical-electrical-thermal-gain...
