摘要

Recent progress in the development of edge-emitting and surface-emitting photonic-crystal distributed-feedback (PCDFB) lasers is reviewed. PCDFB edge emitters have displayed etendues that are no worse than eight times the diffraction limit for stripes as wide as 600 μm. PCDFB surface emitters have maintained optical coherence to pump waists as large as 900 μm with a nearly circular output beam.
