Abstract

This paper discusses micro-and nanoscale coherent light sources, with controlled emission wavelength, direction and polarization, which have important applications in chip-level optical communications, biosensing, and quantum information processing. This paper reports about free-standing microbelt-like optical cavities by embedding a ridge-waveguide in a rolled-up tube structure, formed when a coherently strained InAs/GaAs or InAs/InP quantum dot (QD) layer is selectively released from the host substrate.
