| Summary: | In the past two decades, semiconductor optoelectronic devices (i.e. semiconductor lasers and amplifiers, etc) have played important roles in numerous application areas, especially in telecommunication systems. With the rapid growth of telecommunication market, these devices have been attracting great research interests to improve their single-mode high-power characteristics. Vertical cavity surface emitting lasers (VCSELs) and amplifiers (VCSOAs) are of the most promising devices that have been significantly improved the single-mode high-power performance of semiconductor lasers and amplifiers. Higher operating stability is found to be achievable by implementing antiresonant reflecting optical waveguide (ARROW) to VCSELs and VCSOAs. This doctoral thesis studies the optical characteristics of ARROW VCSELs and VCSOAs through computer modeling and simulation. The main factors (i.e. multi-transverse mode competition, polarization switching, external optical feedback etc.) that may impair the stability of ARROW VCSELs and VCSOAs’ high-power single-mode operation are analyzed numerically. Based on these analyses, design optimization methods are proposed to improve the single-mode high-power performance of ARROW VCSELs and VCSOAs. |
