Abstract:
Glass interposer panels and methods for forming the same are described herein. The interposer panels include a glass substrate core formed from an ion-exchangeable glass. A first layer of compressive stress may extend from a first surface of the glass substrate into the thickness T of the glass substrate core to a first depth of layer D1. A second layer of compressive stress may be spaced apart from the first layer of compressive stress and extending from a second surface of the glass substrate core into the thickness T of the glass substrate core to a second depth of layer D2. A plurality of through-vias may extend through the thickness T of the glass substrate core. Each through-via is surrounded by an intermediate zone of compressive stress that extends from the first layer of compressive stress to the second layer of compressive stress adjacent to a sidewall of each through-via.

A scalable optical interconnect includes a plurality of transmitters, a multiplexing subsystem able to combine the signals of the plurality of transmitters onto one or more transport fibers according to an orthogonal multiplexing scheme, multiple broadband burst-mode receivers structured and positioned so as to be capable of receiving any signal from any one transmitter of the plurality of transmitters, a distribution subsystem structured so as to be able to distribute independently and contemporaneously the signals of every transmitter to every receiver; and one or more selection subsystems structured and arranged so as to be capable of selecting, in less than 1 microsecond, a single channel from within the orthogonal multiplexing scheme. A method and architecture for distributed contention resolution is also disclosed.

Abstract:
An optical switch and WADM uses a channel selector (10) to provide channel selection and reconfigurable operation. The channel selector (10) includes a segmented filter portion (100) and a highly reflecting mirror (110). The channel selectors (10) can be cascaded to form an N-wavelength channel WDM system. The WADM allows for the selection of a wavelength channel from a multitude of channels by moving the appropriate channel selector (10) into the path of the light beam.
Abstract:
Methods and apparatus for combining, adding, and/or dropping channels in optical communication systems that utilize thin film filters without the creation of deadbands, using fiber Bragg gratings (316,322) and additional thin film optical filters, are described. According to one aspect of the invention, an optical filter (318) is used to drop a wavelength (328) range from an optical signal (312). Prior to the optical signal entering the optic al filter, one or more fiber Bragg gratings and an optical circulator (310, 324 ) are used reflects a portion of the communications spectrum which would normally lie with the deadband region of the optical filter. According to another aspect of the present invention, an optical filter (320) is used to combine a first optical signal and a second optical signal to form a combine d optical signal. Neither the first optical signal nor the second optical sign al includes channels within a deadband region of the optical filter. One or mor e fiber Bragg gratings and an optical circulator or a coupler are used to add a third optical signal to the combined optical signal. The third optical signa l includes signal wavelengths within the deadband region of the optical filter .

Abstract:
An array ( 100 ) of honeycomb substrates ( 10 ) comprises honeycomb substrates ( 10 ), a plurality of which have, for each substrate, substrate cells extending from a first end of the respective substrate to a second end and substrate sides extending from the first end to the second end. The substrates of the plurality are arranged in an array with sides of respective substrates facing one another and cells of respective substrates extending in a common direction. One or more channels ( 12 ) are defined by facing substrate sides of two or more substrates of the plurality ( 100 ) and the one or more channels ( 12 ) extend in a direction perpendicular to the common direction.
