Electronic Engineering's Shyqyri Haxha, gets work awarded two patents.

We are proud to announce that Dr Shyqyri Haxha, Reader in Royal Holloway’s Electronic Engineering Department, has recently had two of his research ideas recognized as being both original and practically useful through the award of two patents.

Patent 1: 'A Photonic mixer'; GB Patent Application No. 2000605.2; Named Inventors:  Ian Flint, Taimur Mirza and Shyqyri Haxha

Patent 2: 'An Electro-Optical Modulator'; GB Patent Number 2582199; Named Inventors:  Ian Flint, Taimur Mirza and Shyqyri Haxha

Microwave photonics has unique applications in telecommunication (mobile and fiber optics), satellite and defence sectors, due to its intrinsic benefits such as wide bandwidth, immunity to electromagnetic interference, low loss and high reliability. The backbone of telecommunications is optical fibers transmitting data across a range of high frequencies (up to 40GHz), However, due to the fact that Base Stations are set to operate at a frequency bandwidth that is lower than the operating frequencies used for a cross border transmission, conversion of these frequencies require a unique photonic mixer which can up-convert and down-convert the corresponding frequency signals as appropriate.

These two patents are focused on the optimization and linearization of microwave photonic links and microwave photonic mixers. They will provide unique control over harmonic distortions and will be remove intermodulation distortions for multi-tone frequency mixing. They will have a significant impact in improving ultra-high-speed signal processing in fibre optic communications, mobile communications particularly within the aerospace industry as well as the defence sector.
