1. High efficiency grating-coupled surface-emitting semiconductor lasers
Sammanfattning : .... LÄS MER
2. Study on electroabsorption modulators and grating couplers for optical interconnects
Sammanfattning : Decades of efforts have pushed the replacement of electrical interconnects by optical links to the interconnects between computers, racks and circuit boards. It may be expected that optical solutions will further be used for inter-chip and intra-chip interconnects with potential benefits in bandwidth, capacity, delay, power consumption and crosstalk.

3. Wafer-scale Vacuum and Liquid Packaging Concepts for an Optical Thin-film Gas Sensor
Sammanfattning : This thesis treats the development of packaging and integration methods for the cost-efficient encapsulation and packaging of microelectromechanical (MEMS) devices. The packaging of MEMS devices is often more costly than the device itself, partly because the packaging can be crucial for the performance of the device. LÄS MER
4. Multifunctional Waveguide Grating Couplers for Integrated Optics
Sammanfattning : This thesis describes a novel waveguide component in integrated optics called a multifunctional grating coupler. It couples light in or out of optical waveguides and provides additional optical functions such as beam splitting, arbitrary focusing, polarization sensing, and wavelength separation (wavelength division demultiplexing).

5. Investigation of New Concepts and Solutions for Silicon Nanophotonics
Sammanfattning : Nowadays, silicon photonics is a widely studied research topic. Its high-index-contrast and compatibility with the complementary metal-oxide-semiconductor technology make it a promising platform for low cost high density integration. LÄS MER
