摘要

研究了用于研制中红外表面发射激光器的二维光子晶体(PC)板的角相关反射光谱。PC设计在材料增益频率和第一布里渊区[公式:见文本]点带边缘之间产生完美的共振。因此，我们期望激光发射发生在与板坯表面垂直的方向上。我们制作了PC板，它由具有不同横向截面(即圆形，三角形和五边形)的纳米柱组成的方形晶格组成，并讨论了它们对模态特性的影响。我们认为我们的角度分辨光谱技术将有助于表征用于垂直表面发射量子级联激光器的中红外PC板。

Mid-infrared angle-resolved spectral characteristics of photonic crystal slabs for application in surface-emitting quantum cascade lasers

We study the angle-dependent reflection spectra of two-dimensional photonic crystal (PC) slabs, which we use for developing mid-infrared surface-emitting lasers. The PC design produces a perfect resonance between material gain frequencies and the [Formula: see text]-point band edge in the first Brillouin zone. Hence, we expect laser emission to occur in a direction normal to the slab surface. We fabricate PC slabs, which consist of a square lattice of nanopillars with different lateral cross-sections, i.e., circles, triangles, and pentagons, and discuss their impact on the mode characteristics. We consider that our angle-resolved spectroscopic technique will be useful for characterizing mid-infrared PC slabs to be used in vertical surface-emitting quantum cascade lasers.

期刊介绍： This journal is devoted to the rapidly advancing research and development in the field of nonlinear interactions of light with matter. Topics of interest include, but are not limited to, nonlinear optical materials, metamaterials and plasmonics, nano-photonic structures, stimulated scatterings, harmonic generations, wave mixing, real time holography, guided waves and solitons, bistabilities, instabilities and nonlinear dynamics, and their applications in laser and coherent lightwave amplification, guiding, switching, modulation, communication and information processing. Original papers, comprehensive reviews and rapid communications reporting original theories and observations are sought for in these and related areas. This journal will also publish proceedings of important international meetings and workshops. It is intended for graduate students, scientists and researchers in academic, industrial and government research institutions.
