Fully programmable micro diffraction grating for VIS and near-IR spectroscopic applications
Author(s): R. Lockhart; B. Timotijevic; M. Canonica

Paper Abstract

Programmable Micro Diffraction Gratings (PMDG) are one dimensional arrays of individual mirrors, the height of which can be adjusted to produce a desired spectrum at a given angle. They can function both as spatial light modulators and as reconfigurable generators of high-resolution spectra. Fig. 1a shows the way the PMDG is actuated, while Fig. 1b presents an example of applications for PMDGs, the generation of synthetic spectra [12]. MEMS PMDGs have been used in microspectrometers, compact projection displays, optical communication systems and miniaturized external cavity lasers [1-4] because of their optical properties and compactness.
