Patent ID: 7489837

Claim:
An optical microelectromechanical structure (MEMS) comprising: (i) at least one optically transmissive layer (UTL); (ii) at least one intermediate layer structure (IL); (iii) at least one device layer (DL); (iv) a base layer (BL); and (v) a sealed package wherein the intermediate layer structure (IL) facilitates one or more optical paths (OP) between the optically transmissive layer (UTL) and base layer and wherein the intermediate structure layer (IL) defines a distance (d) between the optically transmissive layer (UTL) and the device layer (DL) within a range of 10-1000 micrometers and wherein the optical paths (OP) for guiding light through the base layer are partly defined by a plurality of holes in a masking deposited on the base layer (BL).
