Abstract

This paper reports the first demonstration of locking the polarization of VCSELs by putting a ultrathin amorphous silicon subwavelength transmission grating in front of the output window of a VCSEL. The operation principle is based on a recent observation that an amorphous silicon subwavelength transmission grating (SWTG) can behave, depending on the ratio of the grating period to the wavelength, either as a polarizer or a waveplate.
