Liquid Crystal Arrayed Microcavities (LCAM) is a new technology forultra-narrow optical filtering (FWHM ~ 0.1 nm) that uses pico-liter volumeFabry-Perot type optical cavities filled with liquid crystal for tuning. LCAMsare sub-nm spectral resolution filters, which utilize well-established laserwriting, thin film deposition, and wafer manufacturing techniques. Thesefilters are compact, robust, and inexpensive. Compact, high-resolution opticalfilters have applications including biomedical imaging, chemical detection, andenvironmental monitoring. Here we describe the LCAM design and initialperformance metrics.
