摘要： The invention provides a low stress optical waveguide assembly wherein one or more waveguide cores have a conformal cladding in register the waveguide core. The core and cladding are preferably lithographically formed on a substrate. A connector assembly provides for the precision interconnection of mating arrays of parallel optical waveguides. The connector assembly has a base with several parallel channel walls cut along a surface of the base. A waveguide assembly is positioned on the base. The waveguide assembly comprises a substrate and one or more transparent, polymeric waveguides on and raised from a surface of the substrate. A conformal cladding is in register with the waveguide core. Such conformal cladding contributes to a reduction in waveguide stress. The waveguide assembly is positioned on the base such that each of the waveguides is set in one of the channels and contacts the walls of the channel. A cover plate holds the waveguide assembly on the base.

摘要： A wavelength selective optical device for locking to a selected wavelength in an ITU grid includes a first waveguide, a second waveguide, a heating element and a control unit. The first waveguide includes a tunable filter formed in the first waveguide and the second waveguide includes a reference filter formed in the second waveguide. The heating element is in thermal contact with the tunable filter and the reference filter and the control unit is coupled to the heating element and the reference filter. The control unit varies a temperature of the heating element responsive to an indication signal provided by the reference filter to adjust the selected channel of the tunable filter.

摘要： The invention relates to lithographically formed, tapered waveguides connectable to optical fibers. A tapered waveguide is formed by imagewise exposing, in an oxygen containing atmosohere, and developing a lithographic composition on a substrate. Exposure is conducted by a converging beam of laser light which has a greater intensity a the bottom surface of the coating composition, a lesser intensity at the top surface, and a gradually decreasing intensity from the bottom surface to the top surface of the coating composition. Either the substrate is moved with respect to the converging beam, or the converging beam is moved with respect to the substrate along a linear path. Either the moving is done at a gradually increasing or gradually decreasing velocity or one gradually increases or decreases the intensity of the beam of laser light along the substrate. After developing and removing the non-polyrnerized portion of the coating composition, a tapered waveguide is fornnd on the substrate. The tapered waveguide may be attached to an optical fiber.
摘要翻译：本发明涉及可与光纤连接的光刻形成的锥形波导。通过在含氧大气中成像曝光并在基板上显影平版印刷组合物来形成锥形波导。曝光是通过会聚的激光束进行的，其具有较大的强度，涂层组合物的底表面，顶表面的强度较小，以及从涂层组合物的底表面到顶表面的强度逐渐降低。基板相对于会聚光束移动，或者会聚光束相对于基板沿线性路径移动。移动以逐渐增加或逐渐减小的速度完成，或者逐渐增加或减少激光束沿衬底的强度。在显影和除去涂层组合物的非多孔化部分之后，在衬底上面还有锥形波导。锥形波导可以附接到光纤。

摘要： Polarization independent optical isolator/circulator devices based on Mach-Zehnder interferometers. The devices utilize either polarization splitting and nonreciprocal polarization conversion or nonreciprocal phase shift within the interferometric arm. For devices with nonreciprocal phase shift, the relative phase difference is 0° in the forward propagation direction and 180° in the backward propagation direction, or vice versa, so that light goes into a bar or cross port depending on the propagation direction. The devices have advantages over previous designs in the use of inexpensive device components, simple alignment, minimal space requirement, and negligible polarization mode dispersion or polarization dependent loss. In addition, the devices can be made in a waveguide form with minimal loss and with high fabrication ease. An additional phase compensator and/or a variable attenuator can be integrated in order to relax the fabrication tolerances.

摘要翻译：基于马赫 - 曾德尔干涉仪的偏振独立光隔离器/循环器。该器件利用干涉测量臂内的偏振分离和非互相偏振转换或非相互相移。对于具有不可逆相移的器件，正向传播方向的相对相位差为0°，反向传播方向的相对相位差为180°，反之亦然，因此根据传播方向，光线进入条形或交叉端口。这些器件在使用便宜的器件组件，简单校准，最小空间要求以及可忽略的偏振模色散或极化相关损耗方面具有优于先前设计的优点。此外，器件可以以最小的损耗和高的制造容易度以波导形式制造。可以集成附加的相位补偿器和/或可变衰减器以便放宽制造公差。
