摘要： An optical structure is fabricated by forming an active layer (204) including a photodefinable material on a substrate (212) or on another underlying layer (202), forming an upper layer (210) above the active layer, and then patterning the active layer by selective application of radiation through the upper layer. The upper layer is substantially transparent to radiation of the type required to activate the photodefinable material in the active layer.

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： 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 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： Optical apparatus with improved center wavelength temperature stability. In an embodiment, an AWG has a plurality of slots inserted along the optical paths. The slots contain one or more compensation materials which collectively correct for an order Q temperature dependency of the AWG base material. Q>=2 or the number of compensation materials is at least 2 or both.

摘要： An integrated optical microstructure includes a substrate (245) carrying an optical waveguide (240) and supporting a medium (210) disposed to receive optical energy from the waveguide. The medium includes an optical re-radiator such as a phosphor (225), which re-radiates optical energy in response to optical energy received from the waveguide. The structure further includes a reflector (250, 255, 260) disposed to redirect some of the input optical energy emanating from the medium back into the medium, to achieve spatial confinement of the input light delivered by the input waveguide. The structure can thereby increase the efficiency of the light conversion processes of re-radiating materials. An aperture (235) in the reflector permits optical energy emitted by the re-radiator to emerge from the structure and to propagate in a preferred direction, such as toward a viewer or sensor. The structure is useful for increasing the brightness of various kinds of small emissive elements which are excited by light delivered from an integrated optical waveguide, including pixels in an information display.

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： In one aspect of the invention, roughly stated, Applicants have discovered that a compensation material within slot elongated in a direction parallel to a segment of waveguide in an arrayed waveguide grating apparatus can compensate for both first and second order change in refractive index of the base waveguide material over temperature. Unlike the transverse slots of conventional linear athermalization techniques, the elongated slot generally parallel to the base material defines a composite waveguide section having a second order effective index of refraction temperature dependency which can be utilized to accurately minimize the temperature dependence of the overall optical path length to both the first and second order. The techniques described herein are also generalizeable to neutralization of the optical path length temperature dependence to any order.

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.
