An optical delay interferometer (ODI) is employed to suppress the pattern effect manifested on a 10 Gb/s return-to-zero (RZ) data stream when amplified by a semiconductor optical amplifier (SOA) operated
in deep gain ...

Phase modulation schemes are attracting much interest for use in ultra-fast optical communication systems because they are much less affected by fiber nonlinearities than conventional modulation formats. Semiconductor ...
This work describes the investigation and development of an optical fibre gas sensor
based on mid infra red absorption spectroscopy. The sensor is suitable for monitoring the gases present in the exhaust emissions of a ...
With the explosive growth in the number of electronic documents available on the
internet, intranets, and digital libraries, there is a growing need for automatic systems
capable of indexing and organising such large ...
Trusted Computing is a relatively new approach to computer security in which a system should be permanently maintained in a well-defined state - and therefore it will reside in a trustworthy state. The word "trustworthy" ...
The capability of a birefringent fiber loop to suppress the pattern effect in a semiconductor optical amplifier is experimentally demonstrated. The results verify that compared to direct signal amplification this scheme ...
The area of wireless sensor networking continues to be one of the most stirring and demanding research domains of this decade. As technology progresses, so do the capabilities of wireless sensor networks: small, low-cost, ...
The widespread adoption of digital control has resulted in many improvements in low
power switching mode power converters. Digital control has introduced alternative
control laws and new features to previously ...
The requirement to measure the real time, dynamic temperature of exhaust system gases
is becoming more and more important in the areas of aeronautics, automotive (cars,
trucks, etc), marine and industrial/environmental ...
This thesis describes an optical fibre sensor to detect and accurately measure
ammonia gas in the agricultural sector. Increases in ammonia emission especially
from the farming industry have created the need for a sensor ...
