摘要： An improvement in the reliability and lifetime of SOI-based opto-electronic systems is provided through the use of a monolithic opto-electronic feedback arrangement that monitors one or more optical signals within the opto-electronic system and provides an electrical feedback signal to adjust the operation parameters of selected optical devices. For example, input signal coupling orientation may be controlled. Alternatively, the operation of an optical modulator, switch, filter, or attenuator may be under closed-loop feedback control by virtue of the inventive monolithic feedback arrangement. The feedback arrangement may also include a calibration/look-up table, coupled to the control electronics, to provide the baseline signals used to analyze the system's performance.

摘要： A silicon-based IR photodetector is formed within a silicon-on-insulator (SOI) structure by placing a metallic strip (preferably, a silicide) over a portion of an optical waveguide formed within a planar silicon surface layer (i.e., "planar SOI layer") of the SOI structure, the planar SOI layer comprising a thickness of less than one micron. Room temperature operation of the photodetector is accomplished as a result of the relatively low dark current associated with the SOI-based structure and the ability to use a relatively small surface area silicide strip to collect the photocurrent. The planar SOI layer may be doped, and the geometry of the silicide strip may be modified, as desired, to achieve improved results over prior art silicon-based photodetectors.

摘要： An silicon-on-insulator (SOI)-based photonics platform is formed to including a venting structure for encapsulating the active and passive optical components formed on the SOI-based photonics platform. The venting structure is used to allow for the encapsulated components to "breathe" such that water vapor and gasses will pass through the package and not condensate on any of the encapsulated optical surfaces. The venting structure is configured to also to prevent dust, liquids and other particulate material from entering the package.

摘要： One or more nanotaper coupling waveguides formed within an optical substrate allows for straightforward, reproducible offset launch conditions to be achieved between an incoming signal and the core region of a multimode fiber (which may be disposed along an alignment fixture formed in the optical substrate), fiber array or other multimode waveguiding structure. Offset launching of a single mode signal into a multimode fiber couples the signal into favorable spatial modes which reduce the presence of differential mode dispersion along the fiber. This approach to providing single mode signal coupling into legacy multimode fiber is considered to be an improvement over the prior art which required the use of an interface element between a single mode fiber and multimode fiber, limiting the number of propagating signals and applications for the legacy multimode fiber. An optical switch may be used to select the specific nanotaper(s) for coupling into the multimode fiber.
摘要翻译：形成在光学衬底内的一个或多个纳米锥耦合波导允许在多模光纤（其可以沿着形成在光学衬底中的对准夹具设置）的入射信号和芯区域之间实现简单，可再现的偏移发射条件，光纤阵列或其他多模波导结构。偏移将单模信号发射到多模光纤中将信号耦合到有利的空间模式，这降低了沿着光纤的差分色散的存在。将单模信号耦合提供给传统多模光纤的这种方法被认为是对需要使用单模光纤和多模光纤之间的接口元件的现有技术的改进，限制了传播信号的数量和遗留的应用多模光纤可以使用光学开关来选择用于耦合到多模光纤的特定纳米锥。
