1. An optical apparatus comprising:
- a two dimensional array of modulator and/or detector pixels embedded in a flexible or deformable body, the modulator and/or detector pixels responding to applied electrical signals to modulate and reflect light impinging the modulator and/or detector pixels; and
an optical arrangement for directing an incoming optical beam onto a selected one or ones of said modulator and/or detector pixels in said array and for returning light which is modulated and reflected by said pixels to an optical transmitter from which the incoming beam was directed to the optical arrangement.

Abstract
A conformal retro-modulator optical apparatus. The apparatus includes an array of multiple quantum well devices disposed in a thin array. A plastic support element is bonded to the thin array, the plastic support element having a thickness greater that of the thin array. The plastic support element is preferably plastic at elevated temperatures above room temperature, thereby allowing the plastic support element and the thin array of multiple well device disposed therein to conform to a predetermined shape, yet being rigid at room temperature.
