Quantum Well Design Basics

By Cadence - 10 Apr, 2024 - Comments: 0

Key Takeaways The choice of materials for the quantum well and barrier layers is paramount. Materials must have compatible lattice structures to minimize defects, with common combinations including GaAs/AlGaAs, InGaAs/InP, and GaN/AlGaN. The width of the quantum well significantly influences the energy levels and density of states, where narrower wells result in greater separation betwe... » read more

Will Co-Packaged Optics Replace Pluggables?

By Bryon Moyer - 14 Oct, 2021 - Comments: 0

As optical connections work their way deeper into the data center, a debate is underway. Is it better to use pluggable optical modules or to embed lasers deep into advanced packages? There are issues of convenience, power, and reliability driving the discussion, and an eventual winner isn’t clear yet. “The industry is definitely embracing co-packaged optics,” said James Pond, principal... » read more
