摘要： A resonant waveguide cavity, preferably a loop, is fabricated from an active material doped host glass and includes a wavelength dispersive lateral coupling designed to preferentially support wavelengths in a selected bandwidth. Pumping light is provided to excite the active material so that the supported wavelengths stimulate in phase emission to increase their amplitude with the amplified signal presented to an output fiber. Where a signal generator is desired, the pumping light can be used to drive the resonant cavity into oscillation to provide a CW output at one of the cavity supported wavelengths.

摘要： A coupling device for coupling two waveguides having different cross sections, for example a layer conductor or laser element to a strip conductor, characterized by a telescopic system, which narrows the beam cross section of the larger of these two waveguides and directs it onto a large cross-sectional end of a tapering waveguide, which tapers down to the cross section of the other waveguide or conductor. The telescopic system can be composed of one conical gradient lens, two coaxial gradient lenses, or a gradient lens coaxially arranged with a conical gradient lens. The tapering waveguide preferably is integral with the strip waveguide or conductor and is of the same type.

摘要： A tunable optical device is produced by forming in the surface of a substrate a fan-shaped grating of continuously varying period by means of a holographic technique using a photoresist and twisted mirrors, coating the surface of the substrate containing the formed grating with a polyurethane film and diffusing a dye in the prescribed region of the resultant polyurethane film coated on the substrate. In the device of the construction described above, irradiation of the region having the fan-shaped grating with a laser light generates laser light beams whose wavelength is variable with the position at which the laser light impinges upon the region of the grating.

摘要： Distributed feedback devices such as distributed feedback lasers are modified by introduction of a central coupling strength discontinuity or other deviation from uniform nature of the distributed perturbations, in order to promote the transmission of oscillation of a single mode in preference over the nearest redundant modes. The class of deviations from uniform coupling strength may be mathematically termed antisymmetric deviations, because they are deviations about the midpoint of the perturbation pattern which result in a distinction of effect of the two halves of the pattern, taking either half as a reference pattern by itself.

摘要： Narrow band wave guide reflectors arranged on a substrate and having wave guide layers with periodic perturbations are tuned by adapting the effective index of refraction n.sub.eff of the wave guide layer to fulfill the Bragg condition of reflection. The index of refraction is adapted by either varying the thickness of the wave guide layer continuously over a width of the layer or by applying a field to a substrate or superstrate comprised of magneto- or electro-optical material to change the index of refraction of the substrate or superstrate.

摘要： A thin film laser typcially operating in the region of 1,000 to 10,000 A. First and second electrodes are mounted in a fluid container in spaced relation with a dielectric block in the gap between the electrodes and fixed to the first electrode. A voltage pulse applied to the electrodes produces an electric field between the electrodes with a discharge occurring in the thin film of fluid between the dielectric and second electrode. The current discharge excites the fluid, forming simple excited molecules which may have a bound upper state and a dissociative lower state connected by an optical transition. The surfaces of the block and second electrode may form an active optical wave guide for the excited molecules, in which lasing occurs. The laser may be tuned by an acoustic wave produced at the surface of the dielectric block which causes distributed feedback in the active region recycling potential laser emission through the active medium and turning the laser to a wavelength that matches the wavelength of the acoustic surface wave.

摘要： Diffracted leaky optical waves are coupled out of a thin film optical waveguide device having one surface which is periodically thickness-modulated or corrugated to form an optical diffraction grating. The waveguide device is constructed such that the average thickness of the waveguide in the complex refractive index of the waveguide or one of the layers surrounding the waveguide is varied when an external power source applied to the device is varied and thereby, a parameter of the leaky wave in accordance with the variable power source. In one embodiment, the waveguide is made of light amplifying material which is suitably excited to produce lasing action and cause an optical wave to propagate in the waveguide. The variable parameter in this case is the wavelength of the leaky wave, and the leaky wave is always normal to the plane of the diffraction grating. Consequently, a tunable laser is provided. In a second embodiment, no lasing occurs, but instead, an external light source is used to cause an optical wave to propagate in the waveguide. The parameter which is varied is the angle between the leaky wave and the normal to the diffraction grating, the wavelength of the leaky wave remaining constant.
