Publication number: 20110116094Abstract: Surface plasmon generation on a metal or semiconductor layer at an outer surface of an optical waveguide, using light reflected or scattered from inside the optical waveguide. One aspect provides a main optical waveguide (11) (e.g. optical fibre) having a second optical waveguide (18) adhered thereto, the second optical waveguide including an optically transparent material (610) separating two surface plasmon supporting layers (600, 620). Another aspect provides a surface plasmon supporting layer of material(s) adhered to the main optical waveguide, the layer having photo-induced regions of material compaction. The regions of compaction may cause un-inscribed refractive index modulations in the main optical waveguide. The surface plasmons are coupled to the guided mode(s) in the main optical waveguide. Surface plasmon resonance depends on sample material in contact with an outermost surface plasmon supporting layer.Type: ApplicationFiled: November 4, 2008Publication date: May 19, 2011Applicant: ASTON UNIVERSITYInventors: Thomas David Paul Allsop, Ian Bennion, David John Webb, Ronald Neal

Publication number: 20090303489Abstract: The generation of surface plasmons on a metal layer arranged upon an outer surface of an optical waveguide, using light reflected from inside the optical waveguide. The reflected light may be a reflected part of guided light travelling along the optical waveguide and may be a back-reflected (e.g. obliquely back-reflected) part of the guided light. The reflected part of guided light may form a radiative optical mode(s) which is used to excite surface plasmons and which is also coupled to the remaining guided mode(s) of the light from which it derives. This coupling of the radiation mode(s) and the guided mode(s) enables changes in the radiation mode(s) to cause consequential changes in the guided mode(s) of light. Such changes in the radiation mode(s) may occur due to the coupling of the reflected mode(s) to the surface plasmons they excite at the metal layer.Type: ApplicationFiled: July 13, 2007Publication date: December 10, 2009Applicant: ASTON UNIVERSITYInventors: Thomas David Paul Allsop, David John Webb, Ronald Neal, Ian Bennion

Patent number: 6580261Abstract: A low current open loop voltage regulator monitor. A circuit is formed with a PTAT current source across a resistor. This current is mirrored by a circuit with two outputs. A first output is formed by a high output impedance current source that has a cascode output. A second output is formed by a higher voltage output current source that has a lower output impedance. The second output feeds an emitter of a PNP device that has its base coupled to the output of the first current source. The output of the first current source and the base of the PNP device are biased above ground by a series of diode and resistor drops that are of the same type comprising the PTAT circuit. This series of devices forms a stack of bandgap voltages that is nominally equal to, but independent of, the regulator output voltage.Type: GrantFiled: May 8, 2002Date of Patent: June 17, 2003Assignee: National Semiconductor CorporationInventor: Ronald Neal Dow
