Paper Abstract

Conventional optical spectrometers that are based on bulk optical components tend to be relatively large and expensive compared to the other components used in systems designed for detecting chemical/biological agents. Microspectrometers based on focusing waveguide gratings incorporate both spectral dispersion and focusing functions into a single component that can be fabricated hundreds at a time at the wafer level using nano-imprint lithography techniques. These types of spectrometers are ideal for integration into micro-fluidic systems because the signals can be directly coupled into the planar waveguide. We present preliminary data from a prototype system and explore potential applications for these devices.
