摘要： Optical structures and method for producing tunable waveguide lasers. In one embodiment, a waveguide is defined within a glass substrate doped with a rare-earth element or elements by ion diffusion. Feedback elements such as mirrors or reflection gratings in the waveguide further define a laser-resonator cavity so that laser light is output from the waveguide when pumped optically or otherwise. Means are disclosed for varying the wavelengths reflected by the reflection gratings and varying the effective length of the resonator cavity to thereby tune the laser to a selected wavelength. Apparatus and method for integrating rare-earth doped lasers and optics on glass substrates. The invention includes a laser component formed from a glass substrate doped with a optically active lanthanides species with a plurality of waveguides defined by channels within the substrate. The laser component may constitute a monolithic array of individual waveguides in which the waveguides of the array form laser resonator cavities with differing resonance characteristics. The channels defining the waveguides are created by exposing a surface of the substrate to an ion-exchange solvent through a mask layer having a plurality of line apertures corresponding to the channels which are to be formed.

摘要： A method of forming a grating in waveguide uses an ion exchange process to provide a waveguide region within and clad by a surrounding substrate and through an ion exchange process diffusing into the substrate an ion, such as such as Ag+ that is photosensitive and that provides a refractive index difference from adjacent non-diffused regions of the substrate. After the diffusion process, the step of exposing at least some of the waveguide region to light having a suitable intensity and duration to provide a permanent index change within regions of the waveguide region to form a grating is performed.

摘要： There is disclosed an optical waveguide comprising a K1-xRbxTiOMO4 single crystal substrate, wherein x is from 0 to 1 and M is P or As, having at least one optically smooth surface wherein sufficient K+ and/or Rb+ have been replaced by ions selected from at least one of H+ and NH¿4?+ and, optionally, at least one monovalent ion selected from Rb?+, Cs+, Tl+¿, and/or at least one divalent ion selected from Ba?+2, Sr+2, Ca+2 and Pb+2¿ to result in the surface index of refraction at least about 0.00025 with respect to the index of refraction of the single crystal substrate. One process disclosed for producing an optical waveguide comprises the steps of contacting at least one optically smooth surface of a single crystal of K¿1-x?RbxTiOMO4 with an ion exchange medium capable of supplying said replacement ions, at a temperature of from about 100 °C to about 600 °C for a time sufficient to increase the surface index of refraction at least about 0.00025 with respect to the index of refraction of the single crystal by replacing K?+¿ and/or Rb+ of said single crystal with said ions supplied by the exchange medium, and cooling the resulting crystal. Another process disclosed for producing an optical waveguide comprises the step of applying a DC voltage of from about 20 V per cm of crystal thickness to about 2000 V per cm of crystal thickness across the z-surfaces of a z-cut K¿1-x?RbxTiOMO4 single crystal, in the presence of a proton source at a temperature of from about -40 °C to 400 °C for a time sufficient to raise the index of refraction underneath the anode by at least 0.00025 with respect to the index of refraction of the single crystal by replacing K?+¿ and/or Rb+ of said single crystal with H+. A nonlinear optic device using the optical waveguide of the invention is also disclosed.

摘要： Le procédé de préparation d'un guide d'onde enterré dans un substrat en verre, selon l'invention, comprend les étapes suivantes:

une étape de réalisation d'un guide d'onde (28,38) par échange d'ions, en surface de chacun de deux substrats (22,32) en verre,
une étape d'alignement des deux substrats, de telle façon que les surfaces dans lesquelles on a réalisé les guides d'onde soient en regard l'une de l'autre,
une étape de fusion directe des deux substrats.

Avantage: le guide d'onde a une section transversale circulaire.

摘要： An optical waveguide device formed out of a material the refractive index of which has anisotropy, and an optical instrument using the same device. The device comprises an electrooptic single-crystal substrate on which are formed a first core portion the refractive index of which is higher than that of the substrate with respect to both ordinary and extraordinary rays of light, and a second core portion the refractive index of which is higher than that of the substrate with respect to extraordinary rays of light only. The overlapping region of the first and second core portions constitutes a double mode waveguide for extraordinary rays of light. This optical waveguide device is used in place of a pinhole element in an optical system in a confocal scanning optical microscope so as to guide illuminating light into an object to be detected, and to guide the reflected light from the object into a detector. This microscope is provided with a polarization conversion element for use in setting the polarization direction of illuminating light different from that of reflected light. The optical waveguide device functions as a single-mode waveguide with respect to illuminating light, and as a double mode waveguide with respect to reflected light.

摘要： L'invention concerne un guide d'ondes optique comprenant un substrat monocristallin de la formule K1-xRbxTiOMO4, dans laquelle x est compris entre 0 et 1 et M représente P ou As, présentant au moins une surface optiquement lisse dans laquelle on a remplacé suffisamment de K+ et/ou Rb+ par des ions choisis entre au moins H+ et NH4+, et facultativement au moins un ion monovalent choisi parmi Rb+, Cs+, Tl+, et/ou au moins un ion divalent choisi parmi Ba+2, Sr+2, Ca+2 et Pb+2 afin d'obtenir un indice de surface de réfraction d'au moins environ 0,00025 par rapport à l'indice de réfraction du substrat monocristallin. Un procédé de production d'un guide d'ondes optiques comprend les étapes consistant à mettre en contact au moins une surface optiquement lisse d'un monocristal de K1-xRbxTiOMO4 avec un milieu d'échange d'ions capable de fournir lesdits ions de remplacement, à une température comprise entre environ 100 °C et environ 600 °C pendant une durée suffisante pour augmenter l'indice de surface de réfraction d'au moins 0,00025 par rapport à l'indice de réfraction du monocristal par remplacement de K+ et/ou Rb+ dudit monocristal par lesdits ions fournis par le milieu d'échange, et à refroidir le cristal obtenu. Un autre procédé de production d'un guide d'ondes optique comprend l'étape consistant à appliquer une tension de courant continu comprise entre environ 20 V par cm d'épaisseur de cristal et environ 2000 V par cm d'épaisseur de cristal dans les surfaces z d'un monocristal de la formule K1-xRbxTiOMO4 à coupe z, en présence d'une source de protons et à une température comprise entre environ -40 °C et 400 °C pendant une durée suffisante pour élever l'indice de réfraction au dessous de l'anode d'au moins 0.00025 par rapport à l'indice de réfraction du monocristal par remplacement de K+ et/ou Rb+ dudit monocristal par H+. Un dispositif optique non linéaire utilisant un guide d'ondes optique de l'invention est également décrit.
