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 for fabricating titanium-indiffusion waveguides in optical modulators and other optical waveguide devices includes disposing titanium strips in a waveguide pattern on the surface of a crystalline substrate, such as lithium niobate or lithium tantalate, and indiffusing the titanium atoms into the crystalline substrate by pressurizing above ambient atmospheric pressure an oxygen gas atmosphere enclosing the crystalline substrate, heating in the oxygen gas atmosphere, maintaining temperature and pressure for an indiffusion period, and cooling to ambient temperature. A powder formed of the same chemical composition as the crystalline substrate may be introduced into the indiffusion process to limit the crystalline substrate from outgassing alkaline earth metal oxide during the indiffusion period. An indiffusion container that allows for crystalline substrates to be annealed in the presence of a powder without contaminating the substrate with the powder during the indiffusion process may be used. Waveguides manufactured in accordance with the method exhibit superior drift performance.

摘要： In one aspect of the invention, a method for pressurized annealing of lithium niobate or lithium tantalate structures, such as optical modulators and optical wave guides, comprises pressurizing an oxygen atmosphere containing a lithium niobate or lithium tantalate structure above normal atmospheric pressure, heating the structure to a temperature ranging from about 150 degrees Celsius to about 1000 degrees Celsius, maintaining pressure and temperature to effect ion exchange or to relieve stress, and cooling the structure to an ambient temperature at an appropriate ramp down rate. In another aspect of the invention a lithium niobate structure such as an optical waveguide or an optical modulator comprises an optically transparent portion that is substantially void of free protons.

摘要： A method of processing a substrate (1) made of a ferroelectric single crystalline material, including the steps of forming a desired proton-exchanged layer (2) in the substrate by proton-exchanging a portion of the substrate, and selectively removing the proton-exchanged layer to form a concave ditch structure (3) in the ferroelectric single crystalline substrate. The desired proton-exchange layer is formed using an acid containing a lithium salt as a proton-exchanging source and the surface of the substrate from which the concave ditch structure is formed is an X-cut surface or a Z-cut surface, as a main surface, of the ferroelectric single crystalline material used as the substrate. The concave ditch structure so formed can have its depth equal to or larger than its half opening width.
