Multi-Wavelength InAs Quantum Dot Microtube Lasers on Si

摘要

In this report, we summarize our work on the design, fabrication, and characterization of multi-wavelength rolled-up quantum dot tube lasers and coherent light sources on GaAs and InP substrates. We also describe the controllable transfer of rolled-up quantum dot tube cavities on Si or any other foreign substrates using fiber abrupt taper assisted transfer technique. The design and fabrication of electrically injected rolled-up quantum dot tube lasers is also presented.
