摘要： A planar lightwave circuit generalized for handling any given band of multiple bands of a wavelength range, including a first grating element handling a first group of bands; and a second grating element handling a second group of bands. The first and second groups of bands overlap in the wavelength range, and may be spaced apart by a fixed wavelength value. By providing two periodic grating elements handling alternating bands, their free spectral range is allowed to expand, improving their roll-off characteristics. By providing separate inputs for each band, wavelength accuracy can be improved. Device flexibility can be further improved by using switch and interleaver fabrics at the inputs and outputs. The resultant device, generalized to handle any given band within a wavelength range, eliminates the need for separate component design and inventory tracking otherwise necessary.

摘要： A flange and packaging assembly characterized by a structural lip configured to impart resistance to thermal-induced deformation (i.e. “stiffness”) to the flange during elevated temperature die attachment processes. The stiffness is achieved through appropriate configuration of the lip (height, width and shape) and is sufficient to at least partially counteract the stresses generated from coefficient of thermal expansion differentials between the flange and a die attached to it. The lip may be molded or otherwise formed with the flange as a unitary lip-stiffened flange, or may be a separate structure that is affixed to the flange. The flange has a lip-stiffened region for die attachment. This region may be raised above the first surface of the substrate base for enhanced stiffening, and may be in the form of a single pedestal supporting a single or multiple die, or may be a series of raised pedestals, each supporting one or more die. The leads may be embedded in a polymetric material that is attached to the flange that is of sufficient thickess to provide the required stiffness. The embedded leads may be shaped and formed so that the desired seating plane height is achieved. The lead form placement can be either on the interior or exterior of the embedded polymetric material. The polymetric material can be supported along the edge of the flange or be seated on a part of an extrusion from the flange.
摘要翻译：一种凸缘和包装组件，其特征在于结构唇缘被配置成在高温模具附接过程期间赋予对凸缘的热诱导变形（即“刚度”）的抵抗力。刚度通过唇缘的适当构造（高度，宽度和形状）来实现，并且足以至少部分地抵消由凸缘和附接到其上的模具之间的热膨胀差异系数产生的应力。唇缘可以模制或以其它方式形成，凸缘作为整体唇缘加强的凸缘，或者可以是固定到凸缘的单独的结构。凸缘具有用于模具附接的唇缘加强区域。该区域可以升高到基板基底的第一表面之上，以增强加强硬度，并且可以是支撑单个或多个模头的单个基座的形式，或者可以是一系列凸起的基座，每个支撑一个或多个模具。引线可以嵌入到具有足够厚度的凸缘附接到提供所需刚度的多边形材料中。嵌入的引线可以被成形和形成，使得实现期望的座面高度。引线形式放置可以在嵌入式多功能材料的内部或外部。多边形材料可以沿着凸缘的边缘支撑，或者从凸缘位于挤压件的一部分上。

摘要： A polarization compensated planar waveguide branch is disclosed having a planar optical trunk waveguide for transporting a linearly un-polarized optical signal having TE and TM modes. A planar optical branch waveguide, capable of supporting TE and TM modes is optically coupled to the trunk waveguide such that at least a portion of an optical signal propagating within the trunk waveguide will couple into the branch waveguide with an undesired imbalance, having stronger TM mode coupling than TE mode coupling for the at least the portion of the optical signal which couples into the branch waveguide from the trunk waveguide. A portion of said branch waveguide downstream from a region where coupling takes place between the trunk and branch waveguides or a waveguide portion optically coupled thereto, receives the at least a portion of the optical signal, and has at least a predetermined bend with a predetermined radius for compensating for the unwanted imbalance in the TM and TE mode caused by light optically coupling into the branch from the trunk waveguide.

摘要： A planar lightwave circuit includes at least one optical waveguide core, and at least one feature proximate the core having a stress-engineered property to balance stress and therefore minimize birefringence affecting the core. A protective passivation layer is formed over the core and the feature to be substantially non-interfering with the balanced stress provided by the feature. The stress balancing feature may be an overcladding layer formed over the core, doped to have a coefficient of thermal expansion approximately matched to that of an underlying substrate, to symmetrically distribute stress in an undercladding between the overcladding and the substrate, away from the core. The protective passivation layer is formed to have a coefficient of thermal expansion approximately matched to that of the overcladding. In one exemplary embodiment, the passivation layer is formed from silicon nitride. Related concepts of stress release grooves, and core overetching, are also disclosed.

摘要： A planar lightwave circuit includes an arrayed waveguide grating (AWG), with input and output waveguides, partially curved array waveguides with respective length differences, and planar waveguide regions for focusing optical energy between the input/output and array waveguides. Optimal waveguide widths and spacing along the planar waveguide region facets are disclosed, which are largely determinative of AWG size and optical performance. Also disclosed are optimal cross-sectional waveguide dimensions (e.g., width and height); modified index of refraction difference between the waveguide core and cladding regions; and optimal array waveguide lengths, path length differences, and free spectral range. These features, especially when combined with advanced fiber attachment, passivation and packaging techniques, result in high-yield, high-performance AWGs (both gaussian and flattop versions).

摘要： A graphical user interface (GUI) provides a design engineer the capability of automatically inserting scan logic and test logic into a design. The graphical user interface includes a scan insertion option for a design engineer to invoke a scan insertion tool to check the design for testability. The graphical user interface also permits the design engineer to invoke a test generation tool such as an automatic test pattern generator (ATPG) tool to check the design for fault coverage. The graphical user interface, which can serve as a front end for a design framework, enables a design engineer to efficiently increase testability while still in a design phase.
