Abstract

Transverse photo-induced voltage (TPIV) in 25 nm-thick Au film with random holes with 100 nm in diameter is measured for linearly, circularly and elliptically polarized light. By rotating the major axis of ellipse of the light, TPIV exhibits specific pattern depending on polarization. The experimental results are readily reproduced by assuming that the angular momentum transfer from the light beam to the film is responsible for TPIV. A novel ellipticity meter is proposed based on this mechanism.
