title: Optical wave-front transformer using the multiple-reflection interference effect inside a resonator.
abstract: We propose a new class of optical wave-front transformer based on a different mechanism that uses the multiple-reflection interference effect in a Gires-Tournois resonator (GTR) as the physical mechanism for phase modification. By coating the front surface of a GTR with a predefined graded reflectivity profile, one can synthesize various optical elements. We present the basic concept of our proposal by synthesizing a lenslike element as a proof-of-principle example. One unique feature of this element is that it can function as a reflecting mirror, a converging lens, or a diverging lens, depending on the resonator length. Other applications are briefly discussed.
