摘要:
A multilayer wire-grid polarizer for polarizing light includes a stack of thin film layers disposed over a substrate, including a wire-grid array of elongated metal elements having lengths longer than a wavelength of the light and a period less than half the wavelength of the light. One of the layers can include a thin film layer with a refractive index greater than a refractive index of the substrate. One of the thin film layers can include a dielectric array of non-metal elements.

An optical data storage system includes a laser diode to produce at least one light beam. An inorganic, dielectric grid polarizing beam splitter is disposable in the light beam to transmit a polarized light beam, and includes a stack of film layers disposed over a substrate. Each film layer is formed of a material that is both inorganic and dielectric. Adjacent film layers have different refractive indices. At least one of the film layers is discontinuous to form a form birefringent layer with an array of parallel ribs with a pitch of less than 390 nm. A drive carries a disc medium disposed in the polarized light beam to reflect a modified light beam. The grid polarizer is disposable in the modified light beam to separate the modified light beam into a reflected beam and a transmitted beam. A photo-detector is disposable in the reflected or transmitted beam.
摘要:
A broadband wire grid polarizer for the visible spectrum has a plurality of elongated elements supported on a substrate. A region having a lower refractive index than the refractive index of the substrate is disposed between the elements and the substrate to reduce the longest wavelength at which resonance occurs. The region may comprise a plurality of ribs extending from the substrate and supporting the elements. The ribs may be formed by etching slots into the substrate using the elements as a mask. The region may also comprise at least one layer of dielectric film. In addition the region may be comprise ribs extending from the surface, each having at least one layer of dielectric film disposed thereon.

A wire-grid polarizer includes a stack of thin film layers disposed over a substrate including a wire grid layer and a plurality of thin film layers disposed between the wire grid layer and the substrate. The wire-grid layer includes an array of elongated metal elements, comprising lengths longer than a wavelength of visible light, a period less than 200 nanometers, a height less than 400 nanometers; and a material selected from the group consisting of aluminum, silver, gold, copper, or combinations thereof. The plurality of thin film layers disposed between the wire grid layer and the substrate include at least one dielectric grid layer and at least one thin film layer comprising silicon. The dielectric grid layer and the wire-grid are substantially parallel with one another, have substantially equal periods, and have substantially equal widths.
