摘要：
Continuous-wave laser action has been achieved in a 2.7 THz quantum cascade device operating on the modes of a two-dimensional photonic crystal resonator. The photonic structure is patterned into the device top metal contact layer. The emission is obtained from the device surface. It is single lobed and highly directional. At cryogenic temperatures the output power is similar or equal to 300 mu W.
