Paper Abstract

Photonic-crystal distributed-feedback (PCDFB) lasers can potentially operate in a single optical mode that remains coherent over extremely large device areas, e.g., > 1 mm2, in spite of the effects of filamentation induced by the linewidth enhancement factor. Two-dimensional diffraction is induced by gratings that are defined on a rectangular lattice for edge emission, or on a hexagonal or square lattice for surface emission. Numerical simulations based on original algorithms reveal that whereas minimizing that product is almost always advantageous in edge-emitting lasers, an optimized surface-emitter should have an intermediate value. We also review recent experimental demonstrations of both 2nd-order and 1st-order optically pumped broad-stripe PCDFB lasers with “W” active regions that emit in the mid-IR.
