Polarization-controlled, single-transverse-mode, photonic-crystal, vertical-cavity, surface-emitting lasers
We developed a polarization-controlled, single-transverse-mode, photonic-crystal, vertical-cavity, surface-emitting laser (PC-VCSEL) by introducing elliptical air holes in the top mirror. TheExpand

Anomalous above‐threshold spontaneous emission in gain‐guided vertical‐cavity surface‐emitting lasers
Anomalously large decrease in spontaneous emission is observed in gain‐guided vertical‐cavity surface‐emitting lasers after the onset of lasing. By analyzing two‐dimensional profiles of the lasingExpand

Effect of size nonuniformities on the band gap of two-dimensional photonic crystals
The effects of size nonuniformities in two-dimensional photonic crystals are studied by using the plane-wave expansion and the supercell methods. Square, triangular, and graphite arrays of dielectricExpand
