Patent ID: 7378655

Claim:
An integrated tunable sensing apparatus for electromagnetic radiation, the sensing apparatus comprising: a substrate comprising a backside and a face, the substrate transparent to incident electromagnetic radiation of a wavelength and having a first reflection device formed on the backside; a tunable cavity region coupled to the backside of the substrate and configured to receive the incident electromagnetic radiation transmitted through the substrate; an elastic material forming a region including the tunable cavity region; the first reflection device within a first portion of the tunable cavity region; a second reflection device within a second portion the cavity region and facing the first reflection device; a movable gap formed between the first reflection device and the second reflection device within the tunable cavity region; an actuation device coupled to the tunable cavity region, the actuation device being adapted to cause movement from a first predetermined spatial dimension to a second predetermined spatial dimension of the movable gap; and a detection device coupled to the tunable cavity.
