Optoelectronics
Spectrum Sliced Photonic Signal Processor 12731 A spectrum sliced photonic processor that has a tunable and reconfigurable finite impulse response filter topology with bipolar taps.
Stabilised poled waveguide 11884 Poling creates a useful non-linearity in glasses; however its lifetime or stability is an issue. This invention provides a means of stabilising the induced non-linearity and substantially extending the lifetime.
Novel Capillaries and Canes for Constructing Microstructured Fibre Preforms 4608 A method of producing polymer holey optical fibre (mPOF) using novel capillary and cane designs that allows the construction of complex holey structures.
An inexpensive all Optical Signal to Noise Ratio (OSNR) Monitor 11016 The invention allows superior control of networks by providing information about the operational state of key network elements. It relies upon a nonlinear process to produce a signal whose average amplitude is a unique function of the optical signal to noise.
A High Repetition Rate, Short Pulse, Self-Starting Laser 11014 This novel design of laser substantially improves on conventional mode-locked lasers. It permits very high repetition rate and reliable self-starting. This is achieved by incorporation of an Semiconductor Optical Amplifier (SOA) in the "Figure of Eight" configuration.
Microstructured Polymer Optical Fibres 3212 Microstructured polymer optical fibres use a pattern of holes running the length of the fibre to achieve their optical effects. They use a single polymer material, and modifications of the microstructure can produce a wide variety of optical effects, some of which are difficult, or impossible to achieve using conventional polymer fibres.
Tunable Optical Supercontinuum Enhancement 11055 The invention enables the spectral power within a narrow band of a broad spectrum of supercontinuum radiation to be significantly enhanced with simple components such as a long period grating in an optical fibre.
Microstructured Polymer Fibres For High Speed Data Transmission 10366 A new type of graded index microstructured polymer optical fibre (GI-mPOF) that can achieve high bandwidths for short-distance data transmission in a variety of applications.

Engineering and Physics
Cutting Pick for Mining Applications 10447 An innovative mining pick for efficiently cutting materials such as coal, rock & iron-ore using existing cutting drums.
Distributed Turbo Coding and Cooperative Transmission Scheme for Wireless Networks 11011 A generalised distributed turbo coding (DTC) scheme for a general relay network with an arbitrary number of relays.
Easily Cleaned Rainwater Guttering 8679 The guttering is profiled to allow full width access for a broom without obstruction from fixings or fittings.
WeldPrint™ – real time quality monitoring in automated welding applications 10808 Signature Image Processing (SIP) technology, known as WeldPrint™, which analyses electrical data collected from welding processes - usually automated, robotic welding - and identifies welding faults in real time, measures the stability of welding, and enables welding processes to be optimised..
