Paper Abstract

A tunable diffraction grating is fabricated by embedding a nitinol wire within an elastomeric grating replica. Curvature of the grating is varied through heating the wire with an electric current. Actuation redirects the grating normal, resulting in a scanning motion of the diffracted beam. With 2.0 A of applied current, the 1st-order beam sweeps from diffraction angle φ = 45.4° to φ = 29.6° (Δφ = 15.8°) in approximately 40 seconds. Use of the deformable grating as a selective color display element is discussed.
