2. Design, Simulation and Characterization of Some Planar Lightwave Circuits
Abstract : Optical devices based on planar lightwave circuit (PLC) technology have the advantages of small size, high reliability, possibility for large scale production, and potential integration with electronics. These devices are widely employed in optical telecommunications, sensing, data storage, imaging, and signal processing. READ MORE

3. Short-range Optical Communications using 4-PAM
Abstract : As the demand for ever higher throughput short-range optical links is growing, research and industry has shown increased interest in multilevel modulation formats, such as the four leveled pulse amplitude modulation, referred to as 4-PAM. As on-off keying persists to be the choice for low latency applications, such as high performance computing, datacenter operators see 4-PAM as the next format to succeed current OOK-based optical interconnects.

4. Multilevel Modulation and Transmission in VCSEL-based Short-range Fiber Optic Links
Abstract : As the demand for ever higher throughput short-range optical links is growing, research and industry associations have shown increased interest in multilevel modulation formats, such as the four leveled pulse amplitude modulation, referred to as 4-PAM. As on-off keying (OOK) persists to be the choice for low latency applications, for example high performance computing, datacenter operators see 4-PAM as the next format to succeed current OOK-based optical interconnects.

5. 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.
