  Liquid Crystal Arrayed Microcavities (LCAM) is a new technology for
ultra-narrow optical filtering (FWHM ~ 0.1 nm) that uses pico-liter 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.
