摘要： Adjacent non-linear optical layers in a stack of at least two such layers are joined by a glass layer to form a device such as a parametric oscillator, frequency doubler or birefringent phase matched device. The indices of the layers and glass are preferably matched within 30%, and for non-linear infra-red or thermally sensitive materials such as gallium arsenide, zinc selenide, lithium niobate and ZnGeP 2 the glass is preferably a low melting chalcogenide glass comprising GE, As, Se ant Te.

IPC分类号： C03C27/6
摘要： Opposed surfaces of two optical components are joined by providing at least one of the surfaces with a thin layer (preferably no more than 100 microns thick) of bonding glass having a glass transition temperature Tg substantially lower than the glass devitrification temperature Tcl, placing the surfaces together with only the coating or coatings therebetween, and heating the assembled components under pressure to a temperature Tb which lies between Tg and Tcl and is sufficiently high to soften the glass and bond the components together. Preferably the bonding glass consists essentially of Ge, As, Se and a relatively high proportion of Te. This is particularly useful for components which are thermally sensitive and/or useful in the infra-red, or where there is difficulty in obtaining a component with an acceptable optical surface.

摘要： An optical substrate is provided with a surface of a desired shape by coating the surface with a thin layer of an optical glass and subsequently modifying the shape of the external surface of the layer. In preferred embodiments, the temperature of the substrate surface is maintained at substantially less than 400 °C, the substrate is an optical component other than a simple window, and the refractive index of the optical glass is within 20 % of the refractive index of the material providing the surface to be coated. One particular use is when both the substrate (e.g. a non-linear optical layer) and the optical glass are optically transmissive in the near infra-red and/or mid infra-red ranges. The glass layer can compensate for physical imperfections in the surface. It can be polished to optical quality, or provided with detail across the coated surface, e.g. as a "moth-eye" anti-reflection layer, or a diffractive or interference structure.

摘要： This invention relates to coded aperture imaging apparatus and methods. In one aspect a coded aperture imager has at least one detector array and a reconfigurable coded aperture mask means. A reconfigurable coded aperture mask means can display various coded aperture masks to provide imaging across different fields of view and/or with different resolution without requiring any moving parts or bulky optical components. More than one detector array can be used to provide large area imaging without requiring seamless tiling and this represents another aspect of the invention. The present invention also relates to the use of coded aperture imaging in the visible, ultraviolet or infrared wavebands. The use of coded aperture imaging for imaging through a curved optical element is taught as the image decoding can automatically remove any aberrations introduced by the curved element.
