2. 1. Growth of ZnO/GaN distributed Bragg reflectors by plasma-assisted molecular beam epitaxy

   Author : David Adolph; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Oxides; GaN; distributed Bragg reflector; MBE; molecular beam epitaxy; ZnO; Nitrides; DBR;

   Abstract : This thesis describes epitaxial growth of ZnO/GaN distributed Bragg reflectors by hybrid plasma-assisted molecular beam epitaxy on GaN(0001). The unique hybrid approach employed the same growth chamber for continuous growth of both ZnO and GaN without exposing the layers to the ambient conditions. READ MORE

4. 2. Ultraviolet vertical-cavity surface-emitting lasers and vertical microcavities for blue lasers

   Author : Filip Hjort; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GaN; ultraviolet; microcavity; electrical conductivity; vertical-cavity surface-emitting laser; AlGaN; electrochemical etching; nanostructures; distributed Bragg reflector;

   Abstract : III-nitride materials are used for ultraviolet (UV) and visible light emitters. One such light source is the vertical-cavity surface-emitting laser (VCSEL) that could find applications within areas ranging from sterilization and medical treatment to car headlights and augmented reality displays.

5. 3. VCSEL Techniques for Wavelength-Multiplexed Optical Interconnects

   Author : Mehdi Jahed; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon photonic integration; vertical-cavity surface-emitting laser; transverse and polarization mode filter; optical interconnect; distributed Bragg reflector.; wavelengthmultiplexing;

   Abstract : The majority of global data communication is taking place within data centers where data is stored and processed and where the largest part of the power used for global networking is consumed. With the rapidly increasing use of Internet-based applications and services, data centers are equipped with a larger number of servers and switches requiring higher bandwidth connectivity. READ MORE

6. 4. Long-wavelength vertical-cavity lasers based on InP/GaInAsp bragg reflectors

   Author : Stefan Rapp; KTH; []
   Keywords : ;

   Abstract : Vertical-cavity surface-emitting lasers (VCSELs) operatingat long wavelength (1.3-1.55µm) are of great interest asinexpensive, high-performance light sources for opticalcommunication systems. READ MORE

7. 5. Free-space cavity optomechanical systems on a chip with III-V heterostructures

   Author : Sushanth Kini; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optomechanics; Micromechanical resonators; Cavity Optomechanics; III-V materials; Photonic crystals;

   Abstract : Cavity optomechanics examines the mutual interaction between light and mechanical motion for controlling mechanical resonators down to the quantum regime. A major challenge in the field of cavity optomechanics remains accessing a strong interaction between the light field and mechanics on the level of single quanta. READ MORE
