Abstract: An optical wavelength division multiplexing (WDM) device comprising optical components that are integrated together to provide an optical WDM that does not require circulators, that has simplified alignment and that is relatively low in cost. The WDM device comprises an integrated port separator (251), a dispersive element (28) and a reflector (30). The integrated port separator comprises various optical components that spatially separate the polarization components of a light beam input (I1,I2) through an input port of the integrated port separator. The spatially separated polarization components are output from the integrated port separator and impinge on the dispersive element, which spatially separates the wavelengths associated with the polarization components impinging thereon. The spatially separated wavelengths then impinge on the reflective element and are reflected with angles of polarization that depend on the state of the reflective element. The reflected polarization components maintain their respective wavelengths when they are reflected. However, when they are reflected, they are directed along a path through the integrated port separator that depends on the angles of polarization of the reflected polarization components, which depends on the state of the reflective element being rotated or not rotated.

Abstract: An arrangement (10) for efficiently shifting energy received at a first wavelength and outputting the shifted energy at a second wavelength. The arrangement (10) includes a laser (12) and an optical parametric oscillator (14) of unique design. The oscillator (14) is constructed with an energy shifting crystal (20) and first and second reflective elements (16) and (18) disposed on either side thereof. Light from the laser (12) at a fundamental frequency is shifted by the crystal and output at a second wavelength. The second wavelength is a primary emission and induces a secondary emission of energy in the crystal. A novel feature of the invention is a coating applied on the reflective elements (16 and/or 18) for minimizing the secondary emission. This constrains the energy to be output by the arrangement (10) at the wavelength of the desired primary emission. In the alternative, the arrangement (10) may be optimized to output one or more of the secondary emissions.

Abstract: PURPOSE: A method and a device for handling optical pulse signals are provided to perform pulse shaping, the treatment of non-linearity and monitoring in optical communication networks in optical fiber links. CONSTITUTION: An SHG(Second Harmonic Generation) optical crystal(30) performs the cascaded SHG with respect to an FH(Fundamental Harmonic) defined by a particular wavelength.

Abstract: 광변조기는전송또는반사된광의강도를제어하기위하여제공된다. 전송모드에서, 분리기는임의적으로편광된광을두 개의편광광선으로분리하며, 두개의광선중하나는다른광선과분리되어전송된다. 재결합기는전기-광학위상지연기가두 개의광선의편광을변경하지않는경우두 개의광선이그것의출력에서재결합되도록한다. 이들광선은지연기에대한전압의함수인양만큼출력을손실한다. 낮은편광모드분광을가지는노오멀-오프버전은재결합기의방향을변경함으로써얻어진다. 낮은편광모드분광을가지는노오멀-온버전은수동적인편광방향회전으로얻어진다. 유사한결과는입력및 출력변조기의동일측면상에있는반사모드에서얻어질수 있다.
