Far field control of large-area surface-emitting photonic crystal quantum cascade laser

Not Accessible

Your library or personal account may give you access

Abstract

Large-area single-mode lasing is demonstrated within surface-emitting photonic-crystal quantum cascade lasers, at room temperature, with narrow divergence (< 1°) and 175 mW peak power. Single-lobed far-field is realized by optimizing the pillar shape.
