Identification of modes and single mode operation of sapphire-bonded photonic crystal lasers under continuous-wave room temperature operation

摘要

Sapphire-bonded photonic crystal laser cavities were fabricated and characterized under room temperature continuous-wave operation, and the single mode lasing with a side-mode-suppression ratio of 28 dB was observed. The lasing modes of the photonic crystal cavities were characterized and compared to calculated spectra from the three-dimensional finite-difference time-domain method.
