Continuous-wave electrically pumped multi-quantum-well laser based on group-IV semiconductors [PDF]
Nature CommunicationsOver the last 30 years, group-IV semiconductors have been intensely investigated in the quest for a fundamental direct bandgap semiconductor that could yield the last missing piece of the Si Photonics toolbox: a continuous-wave Si-based laser. Along this

In-Well and Barrier Coupling Pump of Semiconductor Disk Laser
IEEE Photonics Journal, 2022 We report an in-well and barrier coupling pump scheme of semiconductor disk laser (SDL). An in-well-absorbed (940 nm) and a barrier-absorbed (808 nm) pump source were used to measure laser output characteristics. The output power of the coupling pump can

Ultrashort cavity length effects on the performance of GaInP multiple-quantum-well laser diode
Results in Optics, 2023 The cavity length of a semiconductor laser plays a key role in its operation and dynamic behaviour. Moreover, downsizing the quantum well (QW) laser chip is required for specific applications, such as hard disk drives (HDDs).
