(Color online) FDTD of W15 active waveguide: lasing spectrum (red) compared to the dispersion diagram. Top inset: photonic crystal waveguide as an open resonator. Oblique arrows show Littrow lasing configuration and vertical arrow shows transverse (FP) lasing. Bottom inset: lasing pattern in the -long W15 PhC waveguide.
