摘要

Quarter-wave retardation can be achieved in optical tunneling through a low-index thin film that is surrounded by a medium of higher refractive index, for any index ratio N>2.414, over a range of incidence angles that is determined by N. A novel frustrated-total-internal-reflection circular polarization beam splitter (CPBS) is proposed that uses an adjustable air gap between two Ge prisms. This tunable CPBS operates over a broad (2-12 (mu)m) IR spectral range by controlling the air-gap thickness to match one-tenth of the wavelength of light by use of a piezoelectric transducer.
