Increasing single mode power of 13-μm VCSELs by output coupling optimization
2015
We report on the single mode emission power enhancement of 1.3-mu m VCSELs by adjusting the reflectivity of the top GaAs-based DBR for output coupling optimization using selective removal of Bragg reflector layers. Devices with record single mode power of 6.8-mW at room temperature and 2.8-mW at 80 degrees C, with more than 30 dB single mode suppression ratio, have been obtained.
