Abstract

Phase-locked array of diode lasers is an attractive way to achieve multi-Watt power single-mode operation. Theoretical analysis of the optical modes of planarized phase-locked quantum cascade laser arrays (QCLA) emitting at 4.8 µm was performed in [1], [2]. These high-index-contract photonic crystal (HC-PC) structures allow global coupling between all array elements. Our numerical modelling predicts that even in the presence of strong thermal lensing under CW operation, 3-element QCLA can achieve more than 1W power.
