Abstract
Polarization control is reported for a 2-D independently addressable VCSEL array. Polarization pinning for emitters on the same die at several orientations is achieved by etching trenches close to the contact metallization of each emitter in the array using focused ion beam etching. Polarization extinction ratios in excess of 50 are achieved over a wide range of orientations and bias currents. No significant effects are observed on threshold current subsequent to the etching of polarization pinning trenches.
