Liquid crystal arrayed microcavities (LCAM) is a new technology for ultra-narrow optical filtering (FWHM ∼0.1 nm) that uses picoliter volume Fabry-Perot-type optical cavities filled with liquid crystal for tuning. LCAMs are sub-nm spectral resolution filters, which utilize well-established laser writing, thin film deposition, and wafer manufacturing techniques. These filters are compact, robust, and inexpensive. Compact, high-resolution optical filters have applications, including biomedical imaging, chemical detection, and environmental monitoring. Here, we describe the LCAM design and initial performance metrics.
液晶阵列微腔（LCAM）是一种用于超窄光学滤波（半高宽约0.1纳米）的新技术，它使用填充有液晶的皮升体积法布里-珀罗型光学腔进行调谐。LCAM是亚纳米光谱分辨率滤波器，利用成熟的激光写入、薄膜沉积和晶圆制造技术。这些滤波器紧凑、坚固且价格低廉。紧凑的高分辨率光学滤波器有多种应用，包括生物医学成像、化学检测和环境监测。在此，我们描述了LCAM的设计和初始性能指标。
