MEMS Adaptive Optics Devices: LDRD No. 02-1385 Summary Report

Description: The primary goal of this portion of the LDRD is to develop a vertical programmable diffraction grating that can be fabricated with Sandia's Ultra-planar Multi-level MEMS Technology, the SUMMiT V{trademark} process. This grating is targeted for use in a chemical detection system dubbed the Polychromator. A secondary goal is to design diffraction grating structures with additional degrees of freedom (DOF). Gratings with 2.5 microns of vertical stroke have been realized. In addition, rotational DO… more

High Efficiency Optical MEMS by the Integration of Photonic Lattices with Surface MEMS

Description: This report outlines our work on the integration of high efficiency photonic lattice structures with MEMS (MicroElectroMechanical Systems). The simplest of these structures were based on 1-D mirror structures. These were integrated into a variety of devices, movable mirrors, switchable cavities and finally into Bragg fiber structures which enable the control of light in at least 2 dimensions. Of these devices, the most complex were the Bragg fibers. Bragg fibers consist of hollow tubes in which… more
