摘要： An optical attenuator and method, the optical attenuator having a core which is covered by a cladding material with a section of polymer cladding of an identifiable length. The polymer cladding has an index of refraction that varies with temperature. A thermal device such as a thermo-electric heater or cooler is placed adjacent to the polymer cladding to control the temperature of the cladding. The index of refraction of the polymer cladding is manipulated by changing its temperature by supplying power to the thermal device. The index of refraction of the polymer cladding will range from values below and above the index of refraction of the core material. A light wave transmitted through the core will experience a degree of attenuation due to leakage into the polymer cladding material when the index of refraction of the polymer cladding is equal to or greater than the index of refraction of the core. The light wave may be either attenuated or blocked entirely.

摘要： A low-cost fabrication technique, readily extensible to volume manufacturing is presented for an electro-optically active fiber segment (31) that can be simply integrated into optoelectronic devices. The fabrication technique offers a dielectric isolation structure (16, 17) surrounding the fiber (10) to allow high field poling, a pair of electrodes (37, 38) used both for poling and for inducing an electro-optic effect, and ends of the fiber (18, 19) unaffected by the fabrication and available for splicing with additional fiber sections. The technique is readily adaptable to specialized electrode structures including striplines and/or microstrip lines for high frequency applications and segmented electrodes (52) for quasi-phasematched three-wave mixing applications. By combining the electro-optically active fiber segment (31) with other fibers in an integrated fiber modulator, high frequency modulation of an optical signal may be achieved with applications in telecommunications. By including a Bragg grating structure (53, 54) in the same fiber segment, a remotely accessible electric field sensor is achieved. Three-wave mixing processes in the electro-optically active fiber segment (31) will allow the generation of additional coherent radiation sources in both the visible/UV and infrared spectral ranges.

摘要： An intensity modulator (20) having a Mach-Zehnder structure with first (42) and second (44) waveguide arms formed of an electro-optic polymer. The active molecules of the waveguide arms are poled in first and second different and substantially orthogonal directions. Electrodes (64, 66, 68) are arranged to receive a modulating voltage and generate first and second electric fields which are respectively aligned with the first and second directions. As a consequence, the modulation depth of an optical signal which is transmitted through the modulator is substantially insensitive to the polarization of the signal. Other embodiments combine mode splitters and combiners with first and second Mach-Zehnder modulators which have electro-optic polymer waveguides. The active molecules of the arms of the two Mach-Zehnder modulators are poled in orthogonal directions.

摘要： A method for producing a waveguide for a nonlinear optical device is disclosed. The organic nonlinear optical material 1 is composed of a polymer having the second order nonlinear optical dye moieties substituted for the side chains of the polymer, each end of the optical dye moieties being grafted to the polymer. The optical material 1 is rolled and drawn by rolling rolls 2a, 2b and drawing rolls 4a, 4b, whereby a polymer film 3 is continuously formed, in which the optical dye moieties are oriented in a predetermined direction. Then the resultant polymer films are laminated to be a polymer laminate in which the orientations of the dye moieties are alternately inverted. The polymer laminate is cut in a predetermined direction with a predetermined thickness into a waveguide having a periodic domain structure with a predetermined submicron period or odd number times thereof.
