Spectral response modification via spatial filtering with optical fiber

Abstract: An optical system comprising a frequency modulated laser source adapted to produce a frequency modulated optical beam, an optical spectrum reshaper (OSR) adapted to receive the frequency modulated optical beam from the laser source and convert it into an amplitude modulated optical beam, a focusing lens adapted to receive the amplitude modulated optical beam from the OSR and focus the same, and an optical fiber adapted to receive the amplitude modulated optical beam from the focusing lens and transmit an optical signal; characterized in that the OSR has a central axis, the focusing lens has a central axis, and the optical fiber has a central axis, with the central axis of the optical fiber being laterally offset from at least one of the central axis of the OSR and the central axis of the focusing lens so as to effect spatial filtering and thereby generate the desired optical transmission characteristics for the resulting optical signal in the optical fiber.

Detachable module connector

Abstract: Presented is a detachable module connector comprising a main body with a first section, a second section, and a first opening extending through the first section and the second section, wherein the inner dimensions of the opening in the first section are different from the inner dimensions of the opening in the second section and the opening in the first section is sized to fit around a printed circuit board. The detachable connector is used to couple an electronic module that includes a printed circuit board to a host device. Also presented is a method of building a module using this detachable connector. The detachable connector simplifies the module manufacturing process because the module does not involve the costly hand-soldering and pcb-turning steps of the conventional methods.

Periodic Detection Of Location Of Portable Articles Using An RFID System

Abstract: A system for tracking network devices includes a host computing device, a radio frequency identification (RFID) tag secured to at least one of the network devices, and a reader configured to communicate with the RFID tag to receive device parameters from the RFID tag, the reader being configured to transmit the device parameters to the host computing device.

100-Gb/s and beyond Ethernet optical interfaces

Abstract: First generation 100-Gb/s SMF Ethernet transceiver architecture, standards and components are presented. Second generation architecture, standards and enabling photonic integration component technology are overviewed. Extension of this technology is shown to support cost effective 400-Gb/s SMF Ethernet interfaces.

Optoelectronic transmitter module and method for the production thereof

Abstract: The invention relates to an optoelectronic emission module comprising a housing (B), which has electrical terminal contacts ( 5 ) for supplying and/or carrying away electric signals or for supplying electrical power. Said emission module also has at least one optical emission element ( 13 ), which is arranged inside the housing ( 3 ), and has at least one optical waveguide ( 17 ), which is held inside or on the housing ( 3 ) and in whose injection end ( 19 ) the light emitted by the at least one optical emission element ( 13 ) can be injected. The at least one optical emission element ( 13 ) and the injection end ( 19 ) of the at least one optical waveguide ( 17 ) are mounted on a supporting element. The invention also relates to a method for producing an emission module of the aforementioned type.
