研究了具有二维光子晶体结构的表面发射激光器的激光作用。该光子晶体具有由InP和气孔组成的三角形晶格结构，通过晶圆熔合技术与InGaAsP/InP多量子阱有源层集成。成功观察到基于在六个等效 Gamma-X 方向上传播的光耦合的均匀二维激光振荡，其中有源层的波长被设计为与 Gamma-X 方向的折叠（二阶）Gamma 点相匹配。远场方向图和/或激光光谱的非常窄的发散角被认为反映了二维阻带，也表明激光振荡是相干发生的。 (C) 1999 年美国物理研究所。 [S0003-6951(99)03529-9]。
Lasing action of a surface-emitting laser with a two-dimensional photonic crystal structure is investigated. The photonic crystal has a triangular-lattice structure composed of InP and air holes, which is integrated with an InGaAsP/InP multiple-quantum-well active layer by a wafer fusion technique. Uniform two-dimensional lasing oscillation based on the coupling of light propagating in six equivalent Gamma-X directions is successfully observed, where the wavelength of the active layer is designed to match the folded (second-order) Gamma point of the Gamma-X direction. The very narrow divergence angle of far field pattern and/or the lasing spectrum, which is considered to reflect the two-dimensional stop band, also indicate that the lasing oscillation occurs coherently.
