A simple demonstration of frustrated total internal reflection
We describe a quantitative and inexpensive method of demonstrating frustrated total internal reflection based on the attenuation of a laser beam through a wedge-shaped air gap between two glass prisms. An advantage of this method is that the thickness of the air gap can be determined by observing interference effects with only a slight modification of the setup. The experiment avoids the need t...
متن کاملTotal internal reflection holography for optical interconnections
Planar diffractive optical elements are well suited to fulfill the needs of optical interconnections. They are efficient and can serve as focusing elements, imaging elements, beam deflectors, and fan-out elements. Almost any shape of structure can be realized. This flexibility allows complex and compact interconnections. Two different types of diffractive optical elements exist: the holographic...
متن کاملTime-domain measurements of reflection delay in frustrated total internal reflection.
We present experimental evidence that the contribution of the Goos-Hänchen shift to tunneling delay is suppressed in frustrated total internal reflection. We use a Hong-Ou-Mandel interferometer to perform direct time measurements of reflection delays with femtosecond resolution at optical frequencies, and take advantage of a liquid-crystal-filled double-prism structure to dynamically change the...
متن کاملPrincipal angles and principal azimuths of frustrated total internal reflection and optical tunneling by an embedded low-index thin film.
The condition for obtaining a differential (or ellipsometric) quarter-wave retardation when p- and s-polarized light of wavelength λ experience frustrated total internal reflection (FTIR) and optical tunneling at angles of incidence ϕ ≥ the critical angle by a transparent thin film (medium 1) of low refractive index n1 and uniform thickness d, which is embedded in a transparent bulk medium 0 of...
متن کاملTotal internal reflection fluorescence.
Total internal reflection fluorescence (TIRF) is an optical effect particularly well-suited to the study of molecular and cellular phenomena at liquid/solid interfaces. Such interfaces are central to a wide range of biochemical and biophysical processes: binding to and triggering of cells by hormones, neurotransmitters, and antigens; blood coagulation at foreign surfaces; electron transport in ...
