Abstract

Polydimethylsiloxane (PDMS) was employed to fabricate an elastomeric grating. An aluminum thin film was deposited onto the grating using oblique angle deposition (OAD). The thin film layer enhanced grating reflectivity. Buckling of the metal film was reduced through the use of OAD. At normal incidence, the elastomeric grating demonstrated a maximum scanning capability of 1.24⁰ at an applied strain of 2.69%.
