The　polarization　of　traditional　photonic　crystal　(PC)　vertical　cavity　surface　emitting　laser　(VCSEL)　is　uncontrollable,　resulting　in　the　bit　error　increasing　easily.　Elliptical　hole　photonic　crystal　can　control　the　transverse　mode　and　polarization　of　VCSEL　efficiently.　We　analyze　the　far　field　divergence　angle,　and　birefringence　of　elliptical　hole　PC　VCSEL.　When　the　ratio　of　minor　axis　to　major　axis　b/a　=　0.7,　the　PC　VCSEL　can　obtain　single　mode　and　polarization.　According　to　the　simulation　results,　we　fabricate　the　device　successfully.　The　output　power　is　1.7　mW,　the　far　field　divergence　angle　is　less　than　10　degrees,　and　the　side　mode　suppression　ratio　is　over　30　dB.　The　output　power　in　the　Y　direction　is　20　times　that　in　the　X　direction.
