"Siv.Ing" (M.Sc. equivalent), Physics Engineering, Norwegian Institute of Technology (now Norwegian University of Science and Technology), 1995. 
I did my diploma thesis at SINTEF Instrumentation, section of Microelectronics, group of Microsystems in Oslo. I worked with flip-chip mounted ICs, and the aim of the work was to test reliability due to thermal stress of flip-chip mounted devices. 

Ph.D. Thesis

I started my Ph.D. work in April 1996. The thesis is done under the supervision of Prof. Arne Rønnekleiv and Prof. Sayan Mukherjee. My work is part of a project of development of a tunable semiconductor laser in the mid-IR range, and I am one of four Ph.D. students working with this. The laser structure will be grown by MBE (molecular beam epitaxy). 

My part of the work is clean-room processing and testing. To make the lasers useful for gas sensing some kind of mode stabilization and tuning structure is also required. We have some ideas for what structures to use, and at the moment I'm doing some calculations on the waveguides using BPM and by setting up simplified solutions and solving the dispersion relation.

The fall semester of 97 I spent at Center for high Technology Materials,

Formal description of my thesis

Mid-IR semiconductor lasers for environmental sensing

The Ph.D. study is part of a university program at Dep. of Physical Electronics concerning development of mid-IR diode lasers (NFR project no. 107617/420). The project is to develop single mode tunable lasers for gas spectroscopic applications to environmental and industrial sensing/monitoring. Required techniques for material growth, design, fabrication and testing is to be developed. 

The following areas are to be studied, with emphasis on gas spectroscopic applications: 

  1. Applications for use of spectroscopy. Which wavelengths are best suited, and what are the requirements for tuning? Mostly theoretical work.
  2. Tunability. There are three principles for tuning of a diode laser:
  • Temperature tuning. 
  • Use of gratings to stabilize lasing modes. 
  • Divided waveguide, or Y-branch lasers for current tuning.
Both theoretical and experimental work will be done. 
  • Waveguides. Theoretical and experimental work., in support of item 2.

All laser processing is carried out in the NTNU cleanroom (Norwegian only). The thesis is expected to be finnished in the fall of 2001. Meanwhile, I've started to work for SINTEF Microsystems in Oslo.
