The optical reflector comprises a glass substrate, on which are piled up a film of refractive index n1, a film of refractive index n2, a film of refractive index n3, and a film of refractive index n4, sequentially, wherein the thickness of the films are adjusted so that a relationship, n1≧n4>n3>n2, is established among those refractive indices n1, n2, n3 and n4. The film of refractive index n2 is from 30 nm to 60 nm in the film thickness, a reflectivity to visible light is equal to or greater than 75% upon the surface of the film of refractive index n4, and the value {(a*)2+(b*)2}½ is from 0 to 10 when representing the color tone of reflected light upon this film by a* and b* (psychometric chroma coordinates).

摘要： Negative Group-delay-dispersion mirror (NGDD-mirror) multilayer structures include a generally-orderly arrangement of layers or groups of layers in which the function of certain individual layers or groups of layers can be recognized and defined. The structures are broadly definable as a rear group of layers which are primarily responsible for providing a desired reflection level and reflection bandwidth together with a low and smoothly varying reflection phase-dispersion, and a front group of layers which are primarily responsible for producing high reflection phase-dispersion necessary for providing a desired NGDD level and bandwidth. The front group of layers relies on multiple resonant trapping mechanisms such as two or more effective resonant-cavities, employing one or more sub-quarter-wave layers to shape the phase-dispersion for providing a substantially-constant NGDD. In certain embodiments of the structures, a base layer or substrate of a highly-reflective metal can be used to reduce the number of dielectric layers needed to provide high reflectivity.

摘要： A highly damage resistant, multilayer, optical reflective coating includes alternating layers of doped and undoped dielectric material. The doping levels are low enough that there are no distinct interfaces between the doped and undoped layers so that the coating has properties nearly identical to the undoped material. The coating is fabricated at high temperature with plasma-assisted chemical vapor deposition techniques to eliminate defects, reduce energy-absorption sites, and maintain proper chemical stoichiometry. A number of differently-doped layer pairs, each layer having a thickness equal to one-quarter of a predetermined wavelength in the material are combined to form a narrowband reflective coating for a predetermined wavelength. Broadband reflectors are made by using a number of narrowband reflectors, each covering a portion of the broadband.
