摘要： Roughly described, arrayed waveguide grating apparatus includes one or more input and/or output waveguides which are shaped and oriented such that optical energy communicated with the waveguide array is, within a distance of no more than l mm into the mouth of the waveguide, directed substantially in-line with the optical centerline of the waveguide. In one embodiment, the waveguides are shaped and oriented such that the optical energy enters or exits the waveguide substantially-line with the optical centerline of each waveguide. In another embodiment the waveguides are shaped and oriented such that optical energy is, at the mouth of each waveguide, directed off- axis, and the waveguide includes mode conversion means such that optical energy is directed substantially in-line with the optical centerline within a distance of no more than l mm into the mouth of the waveguide. The mode conversion means may, for example, include a non-adiabatic lateral optical centerline shift.

摘要： A tunable optical waveguide chip for optical transforms. Roughly described, the chip includes a planar waveguide having a lens region and a plurality of individually addressable energy applicators distributed transversely across an optical path through the lens region. By individually controlling the energy applied to each of the energy applicators, a desired index of refraction profile can be induced in the lens region transversely across the optical path for performing any of a variety of optical transforms. The device may include an upstream AWG which focus a wavelength de-multiplexed signal on a focal plane within the lens region. The applicators may be thermo-optic or electro-optic, for example.

摘要： Roughly described, an AWG has two or more inputs and multiple outputs. By selecting the angular spacing among the inputs, and by designing the different inputs to address different orders of the waveguide array, the device can be designed such that the inputs will carry frequency bands having any desired center frequency spacing and any desired same or different channel spacing. For example a dual input device can be designed such that one input carries C- band channels and the other input carries L-band channels, and both have channel spacings that match or substantially match the ITU grid.

摘要： A redundant optical connection system is manufactured in specially prepared form to allow optical connections to be made at a later step. In response to information specifying which of the optical sources are functional, further structure may be activated or introduced into the connection system which guides optical energy to optical outputs from only those of the sources that are functional. In one aspect of the invention, the preliminary form includes primary guiding structures coupling each of a plurality of primary optical sources to a respective application structure, and a secondary guiding structure coupled to a secondary optical source and terminating without yet coupling to any application structure. If the information indicates that one of the primary optical sources in non-functional, then structure can be added or activated which transfers optical energy from the secondary guiding structure into the primary guiding structure corresponding to the non-functional source. In another aspect of the invention, the preliminary form includes a material having N optical sources and more than N output guiding structures. A gap region is provided in the material between the outputs of the optical sources and the inputs of the output guiding structures. Additional guiding structures are later formed or activated in response to the information, to guide optical energy to the inputs of the output guiding structures from only functional ones of the optical sources.

摘要： Roughly described, an optical device has first and second waveguide segments which are constructed such that irradiation changes both average refractive index and also birefringence in the respective segment. The change in birefringence as a function of the change in average refractive index, is different for the two segments. Predetermined lengths of each of the two segments are irradiated. In an MZI, the technique can be used to adjust simultaneously for one or more of differential path length phase delays, coupler-induced phase errors, and frequency errors.

摘要： A thermo-optic switch is operated in a novel near-impulse mode in which the drive pulse width is shorter than twice the diffusion time of the switch. The drive pulse width is less than the rise time of the steady-state optical response and also less than the rise time of the deflection efficiency response to the applied drive pulse. The drive pulse can further include a sustaining segment following the initial short pulse segment, if it is desired to maintain the switch in an ON state for a longer period of time. A number of additional techniques are described for further reducing the response time of the switch. An array of thermo-optic switches operated in this manner can form a display which, due to the fast individual switch rise times, can operate at an overall fast refresh rate.
摘要翻译：热电开关以新颖的近脉冲模式工作，其中驱动脉冲宽度短于开关扩散时间的两倍。驱动脉冲宽度小于稳态光响应的上升时间，也小于对所施加的驱动脉冲的偏转效率响应的上升时间。如果希望将开关保持在接通状态较长的时间段，则驱动脉冲还可以包括跟随初始短脉冲段的维持段。描述了一些额外的技术来进一步减少开关的响应时间。以这种方式操作的一组热电开关可以形成显示器，由于快速的单独开关上升时间，可以以整体快速刷新率进行操作。

摘要： A device for variable attenuation of an optical channel includes an elongated core surrounded by a cladding. Optical energy propagating along the longitudinal axis of the core is normally confined thereto by the difference in refractive indices between the core and cladding. The thermo-optic coefficients of the core and cladding are closely matched such that waveguide confinement is substantially invariant with respect to ambient temperature. The device further includes a thermal source arranged above the core. The thermal source is operable to generate a temperature gradient of controllable magnitude along a vertical axis extending through the core. The temperature gradient causes reduction of the local refractive index within the core relative to surrounding regions of the cladding such that a portion of the optical energy is deflected away from the thermal source and extracted from the core.
