制作并测试了采用锌扩散无序空间模式滤波器的刻蚀柱底发射垂直腔面发射激光器（VCSEL）。滤波器成功地抑制激光的高阶横模VCSEL直径大于11 /spl μ/m，同时获得高达1.5 mW的输出功率与阈值电流低至2.7 mA。发射完全是单模，模式抑制比大于25 dB，最高输出功率电平。
Etched pillar, bottom emitting vertical cavity surface emitting lasers (VCSELs) employing a zinc diffused and disordered spatial mode filter are fabricated and tested. The filters successfully suppress lasing of higher order transverse modes in VCSELs with diameters greater than 11 /spl mu/m, while obtaining output powers of up to 1.5 mW with threshold currents as low as 2.7 mA. Emission is entirely single mode, with mode suppression ratio greater than 25 dB up to the highest output power levels.
