Photonics: lasers producing tailored beams

Compact lasers that can produce a range of beam patterns are important for progress in several areas, including the improvement of optical tweezers, ultra-high-density optical memory and microfluidics. Here we engineer photonic crystals to generate semiconductor lasers that produce a range of beam patterns while maintaining stable single-mode oscillation. Our results could contribute to the realization of compact lasers that are capable of producing diverse beam patterns on demand.

Photonics: tuning holes in photonic-crystal nanocavities

One challenge in photonics is strongly to confine light in small volumes in order to increase light-matter interaction. Akahane et al. propose a new concept for increasing the lifetime of this interaction, based on tailoring of the Fourier spectrum of cavity modes, which they believe is demonstrated by the surprising enhancement (roughly tenfold) of the quality factor Q of the cavity as a result of fine-tuning the mirror-hole geometry in a photonic-crystal nanocavity. Here we question the validity of their concept and argue that the improvement in Q is due to an increase in the impedance wave matching at the cavity edges and to a slow-wave effect. This alternative interpretation opens the way to new cavity designs.

用于整体光照的最小方差抽样

蒙特卡罗随机抽样算法合成的图像往往带有噪声,为了减少图像的噪声,提出了一种新的图像平面自适应抽样方法.直接光照抽样和间接光照抽样的方差及耗时有很大的差异,有必要自适应分配这两种抽样的数目.每个像素每种光照的抽样数目由直接光照和间接光照的方差和耗时来决定,根据拉格朗日乘子法将直接和间接光照的抽样自适应地分配到图像平面中,使得在给定的时间里图像的方差接近最小值.根据实验结果,与已有方法相比,新方法渲染的图像的方差降低了11.5%～56.9%.
