Title: Mark E Bray: Innovator in Optical Amplification Technology
Introduction
Mark E Bray is a notable inventor based in Paignton, GB. He has made significant contributions to the field of optical amplification technology, holding 2 patents that showcase his innovative approach to enhancing optical systems.
Latest Patents
One of Bray's latest patents is titled "Method and apparatus for the measurement of erbium optical amplifiers." This invention presents an inexpensive broadband source, such as an ASE source, for measuring erbium amplifiers. The results indicate that the deltas for gain and noise figure are less than 0.4 and 0.3 dB, respectively. The spectral loading used for testing erbium amplifiers closely resembles field conditions, and while the ITU grid is a common solution, it can be costly and may limit spectral resolution. Bray's high power amplified spontaneous emission source offers a cost-effective alternative that performs comparably to ITU grid measurements, with the measurement's spectral resolution only limited by the optical spectrum analyzer's capabilities.
Another significant patent by Bray involves the use of optical amplifiers in WDM optical transmission systems. This invention describes a supervisory signal channel that monitors and controls the operation of amplifiers, which is spectrally separated from data transmission. The construction of the amplifier allows for upgrades to the transmission system, enabling additional data handling capacity without interrupting the existing data transmission path. This is achieved through the use of channel dropping and insertion filters, ensuring seamless operation during upgrades.
