15 Oct 2003TL;DR: In this article, a cable television return link system that provides dedicated, high-speed, full-duplex and point-to-point connections between users and the head end system is disclosed.
Abstract: A Cable Television (CATV) digital return link system that provides dedicated, high-speed, full-duplex and point-to-point connections between users and the head end system is disclosed. The CATV digital return link system includes return path transmitters, intermediate hubs and a head end hub coupled to each other via a network of fiber optic cables. The return path transmitters are each coupled to a relatively large number of users via a local CATV-subtree. Signals from cable modems are transmitted via the local CATV-subtree to the return path transmitters for transmission to the head end. The return path transmitters include circuitry for digitally processing the RF data from the subtree prior to transmitting the RF data to the head end.

15 May 2007TL;DR: In this paper, a method for depositing protective coatings on front and rear facets of an optical device, such as a laser die, is disclosed, which helps prevent laser facet damage common to laser dies manufactured using known processes.
Abstract: A method for depositing protective coatings on front and rear facets of an optical device, such as a laser die, is disclosed. The protective coatings help prevent laser facet damage common to laser dies manufactured using known processes. In one embodiment, the method for coating the laser die includes placing the laser in an evacuated coating chamber before applying a first coating portion to a first facet of the laser. The first coating portion is applied to the first facet so as to form a protective covering thereon, but is applied at a coating energy that minimizes damage to the as-yet uncoated second facet. The laser is then rotated within the coating chamber, and a full coating is applied to a second facet of the laser. The laser is again rotated, and a full coating is applied atop the first coating portion to the first facet of the laser.

17 May 2013TL;DR: A phase-locked loop circuit may include a first circuitry to receive a reference signal and a source signal, and a second circuitry may generate a digital signal for demonstrating a phase-to-digital conversion of the correction signal as discussed by the authors.
Abstract: In an example embodiment, a phase-locked loop circuit may include a first circuitry to receive a reference signal and a source signal. The first circuitry may generate a correction signal for demonstrating a difference in phase between the reference signal and the source signal. The phase-locked loop may include a second circuitry to receive the correction signal. The second circuitry may generate a digital signal for demonstrating a phase-to-digital conversion of the correction signal. The phase-locked loop may include a third circuitry to receive the digital signal. The third circuitry may generate a control signal for demonstrating a converted voltage of the digital signal. The phase-locked loop may include a fourth circuitry to receive the control signal. The fourth circuitry may generate the source signal in response to the control signal.

21 Aug 2002TL;DR: In this paper, an optical component mounting apparatus is presented for accurate mounting of optical components without the use of epoxy or other affixing agents, where the body of the body includes an outer sidewall disposed between the first and second ends, wherein the inner and outer sidewalls define a second component holding region.
Abstract: Embodiments of the invention provide for an improved optical component mounting apparatus and method. In one embodiment, the invention provides an optical component mounting apparatus that provides for accurate mounting of an optical component without the use of epoxy or other affixing agents. The optical component mounting apparatus includes a body having a bore formed longitudinally therethrough between a first and second end. The body also includes an inner sidewall of the body disposed adjacent the first end that defines a first component holding region. The first component holding region is in an offset alignment with the bore, the inner wall is adapted to frictionally accept a first component therein and exert a biasing force thereon to maintain the first component in a desired optical alignment. In another embodiment, the body includes an outer sidewall disposed between the first and second ends, wherein the inner and outer sidewalls define a second component holding region therebetween. The inner and outer sidewalls are adapted to frictionally accept a second component therein and exert a biasing force thereon to maintain the second component in a desired alignment relative the bore.

05 Jan 2015TL;DR: A VCSEL can include a graphene intra-cavity absorber having at least one graphene region and at least 1 dielectric region adjacent to the graphene region as discussed by the authors.
Abstract: A VCSEL can include a graphene intra-cavity absorber having at least one graphene region and at least one dielectric region adjacent to the graphene region. The VCSEL can also include a graphene electrode electronically coupled with at least one graphene region. The VCSEL can also include a contact region adjacent with at least one dielectric region. The VCSEL can also include a contact electrode electronically coupled with the contact region. The VCSEL can also include a base electrode electronically coupled with a base of a semiconductor region of the VCSEL. The graphene intra-cavity absorber can include at least two graphene regions sandwiching at least one dielectric region therebetween.
