英文摘要 | Multi-component barrier layers include formation of a GaAs layer and at least one adjacent GaAsN layer. The resulting multi-component barrier layer shape can provide enhanced (extended) offset for capture of holes and enhanced electrons. Other benefits include: a small amount of strain compensation; poorer spatial overlap of higher confined states reducing parasitics at high bias, with some small effect on the lowest confined states. Quantum wells and associated barriers layers can be grown with combinations of gallium, (Ga), arsenic, (As), nitrogen (N), aluminum (Al), antimony (Sb), phosphorous (P) and/or indium (In) placed within or about a typical GaAs substrate to achieve long wavelength VCSEL performance, e.g., with wavelengths over 1200 nm. Layers of strained quantum well material can also be supported by mechanical stabilizers. |
