Photonic MEMS and structures
First Claim
1. A device comprising:
- a substrate;
a transparent conducting layer disposed over the substrate;
an absorber layer disposed over the substrate, wherein the absorber layer includes a semiconductor;
a reflector disposed over the substrate; and
an optical resonant cavity between the absorber layer and the reflector,wherein a portion of incident light passing through the substrate is reflected by the reflector towards the absorber layer.

Abstract
An interference modulator (Imod) incorporates anti-reflection coatings and/or micro-fabricated supplemental lighting sources. An efficient drive scheme is provided for matrix addressed arrays of IMods or other micromechanical devices. An improved color scheme provides greater flexibility. Electronic hardware can be field reconfigured to accommodate different display formats and/or application functions. An IMod'"'"'s electromechanical behavior can be decoupled from its optical behavior. An improved actuation means is provided, some one of which may be hidden from view. An IMod or IMod array is fabricated and used in conjunction with a MEMS switch or switch array. An IMod can be used for optical switching and modulation. Some IMods incorporate 2-D and 3-D photonic structures. A variety of applications for the modulation of light are discussed. A MEMS manufacturing and packaging approach is provided based on a continuous web fed process. IMods can be used as test structures for the evaluation of residual stress in deposited materials.
