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: Optoelectronic and photonic devices (100) are formed by employing polymer materials that have a lower glass transition temperature (Tg) than the nominal operating temperature. By using such materials, the local or segmental mobility is increased so that local stress is eliminated or minimized on the polymer material, making performance more robust. The current invention involves use of polymer in an optical device (100) in an operating temperature range in the region above Tg, where the polymer segments between crosslinks are allowed local freedom of movement; however, the large-scale movement of the material may be restricted by the crosslinked structure of the polymer material. The temperature operating point of a device constructed according to the invention is thus preferably distance from both the viscoelastic region near Tg and from the glassy region below Tg.

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 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.
