Single-Mode VCSELs modes are suppressed by mode selective gain or loss. In each case we present the current state-of-the-art and discuss pros and cons. At the end, a specific example with experimental results is provided and, as a summary, the most promising designs based on current technologies are identified.作者: 高原 時(shí)間: 2025-3-22 22:45
Polarization Control of VCSELson-dependent reflectivity. It has turned out that the last approach is most promising. It can be realized by incorporating a shallow surface grating in the upper mirror of a top-emitting VCSEL. Several million grating VCSELs are in reliable operation meanwhile, mainly in optical computer mice.作者: 錯(cuò) 時(shí)間: 2025-3-23 02:51

Polarization Control of VCSELslinearly polarized, its orientation is not well defined. This is because both the resonator and the gain medium are quasi isotropic in the plane of the active layers. Since a stable polarization is required for almost all sensing and some datacom applications, extensive and in-depth investigations h作者: Infraction 時(shí)間: 2025-3-24 14:16
Polarization Dynamics of VCSELsriments have shown that VCSELs emit a linearly polarized fundamental transverse mode either along the [110] or . crystallographic direction. Polarization switching between these modes can occur when the injection current is increased, showing either a frequency shift from the higher to the lower fre作者: 偶然 時(shí)間: 2025-3-24 16:22
