First CW operation of 1.3 /spl mu/m-range GaInNAsSb VCSELs and VCSEL array
2002
First CW operation of 1.3 /spl mu/m-range VCSELs and VCSEL array using GaInNAsSb quantum wells on GaAs substrates are reported. The threshold voltage is as low as 1.2 V, which is the lowest value ever reported for 1.3 /spl mu/m-range GaInNAs-based VCSELs, and the threshold current. of 10ch-array are as uniform as 1.85 /spl plusmn/ 0.15 mA at 25/spl deg/C.
