摘要： The invention relates to a method and circuit for aligning a serial bit stream with a parallel output. The method comprises latching Q bits from the serial bit stream into a register, locating a position P of a first bit of a start of frame delimiter (SFD) in the register and discarding P-1 bits from the serial bit stream, before the position of the first bit of the SFD, thereby aligning the serial bit stream with the parallel output. The circuit comprises a latch, a fault tolerant analysis logic (FTAL) for locating a position P of a first bit of a start of frame delimiter (SFD) in the register and a shift register for discarding P-I bits from the serial bit stream, before the position of the first bit of the SFD, thereby aligning the serial bit stream with the parallel output.

摘要： This disclosure teaches an optical transposer that provides "passive" alignment between optical waveguides in a silicon photonics die (10) seated within a receptacle (24) that is formed in a body member (22) of the optical transposer and corresponding optical waveguides (28) that are precisely dimensioned and located within the body member via laser scribing. The manufacturing method and optical transposer configuration taught herein allow for essentially automated placement (e.g., seating and gluing) of silicon photonics dies within corresponding optical transposer receptacles, without need for controlling final die alignment/placement as a function of measured optical insertion loss. In particular, such passive alignment is obtained via accurate dimensioning of the receptacles relative to the dies and by precise positioning of the entry points into the receptacles of the optical waveguides that are laser scribed into the body member of the optical transposer.
摘要翻译：该公开内容教导了一种光学转换器，其在位于光学转换器的主体部件（22）中的硅光子管芯（10）中的光学波导之间提供“无源”对准，所述插座（24）形成在光学转换器的主体部件（22）中并且对应的光波导（28 ），其通过激光划线精确地定尺寸并位于身体构件内。本文中教导的制造方法和光学转换器配置允许在相应的光学转换器插座内基本自动地放置（例如，将硅光子管芯放置和粘贴），而不需要根据测量的光插入损耗来控制最终的芯片对准/放置。特别地，这种无源对准是通过插座相对于管芯的精确尺寸以及通过将入射点精确地定位在激光划分到光学转换器的主体部件中的光波导的插座中而获得的。

摘要： Optical waveguide coupling ratios can be modified for a package by providing a substrate (104) with a photonic circuit (108) disposed on a first section (103) of the substrate (104) and a plurality of optical waveguides (100) formed in glass (110) disposed on a second section (105) of the substrate (104), the waveguides (100) being connected to the photonic circuit (108), adjacent ones of the waveguides (100) having a fixed coupling ratio. A three-dimensional region of the glass (110) abutting an end of one or more of the waveguides (100) is lased (112) to change a refractive index of the glass (110) in each three-dimensional region, and thereby extend a length of each waveguide (100) abutting one of the three-dimensional regions so that the coupling ratio between that waveguide (100) and an adjacent waveguide (100) is changed as a function of the extended length. The lasing (112) is controlled based on feedback (118) so that each coupling ratio changed by the lasing (112) varies by less than a target amount.

摘要： A wavelength converter includes first silicon waveguides (102) and second silicon waveguides (104) intersecting the first silicon waveguides (102) to form an arrayed waveguide (100). The arrayed waveguide (100) receives optical data signals at the same wavelength at a first input (106) and optical pump signals at different wavelengths at a second input (108). Microring resonators (114, 116) evanescently couple different ones of the first silicon waveguides (102) to different ones of the second silicon waveguides (104). Each microring resonator (114, 116) is tuned to the wavelength of the optical data signals or one of the wavelengths of the optical pump signals, so that different combinations of the optical data signals and the optical pump signals are provided at an output (120) of the arrayed waveguide (100). A non-linear optical media (200) converts the wavelength of each combined optical signal at the output (120) of the arrayed waveguide (100) to yield wavelength converted signals each having a new dedicated wavelength.
