1. Applications of monolithic fiber interferometers and actively controlled fibers
Abstract : The objective of this thesis was to develop applications of monolithic fiber devices and actively controlled fibers. A special twin-core fiber known as a ‘Gemini’ fiber was used to construct equal arm-length fiber interferometers, impervious to temperature and mechanical perturbations. READ MORE

2. Technology for photonic components in silica/silicon material structure
Abstract : The main objectives of this thesis were to develop a lowtemperature PECVD process suitable for optoelectronicintegration, and to optimize silica glass composition forUV-induced modifications of a refractive index in PECVDfabricated planar devices. The most important achievement isthe successful development of a low temperature silicadeposition, which for the first time makes it is possible tofabricate good quality low loss integrated components whilekeeping the temperature below 250oC during the entirefabrication process.

5. Reconfigurable and transparent wavelength division multiplexed optical transport networks
Abstract : This thesis is about reconfigurable and transparentwavelength division multiplexed (WDM) networks.Reconfigurability is used to achieve higher surveillance andthroughput in the network. This is done by wavelength selectiveand independent network elements. These network elements canaccomplish bypass and protection switching ofthe traffic. READ MORE
