Abstract :
We present a monolithic technique for simultaneous mode and polarization control in oxide-confined VCSELs using a locally etched sub-wavelength surface grating. A single-fundamental mode emission with an SMSR>30 dB and an OPSR~20 dB is achieved over the entire operational current range, with a maximum output power of 4.1 mW
