Reconfigurable Optical Elements Based on Single and Coupled Microdisk Resonators with Quantum DOT Active Media
Abstract
We developed a low cost technique for incorporating colloidal quantum dots into active photonic structures with the end goal of realizing bistable lasing structures. To this end we successfully demonstrated (i) incorporation of CdSe QDs into polymer and dielectric host and realization of devices such as active waveguides, microdisk and microring resonators, surface emitting microcavity structures, and distributed feedback (DFB) grating structures, (ii) gain and amplified spontaneous emission (ASE) from a vertical cavity surface emitting structure, (iii) gain and lasing like emission from planar DFB grating structures fabricated using softlithography, (iv) protocol for developing surface emitting and DFB lasers using colloidal QDs as the active medium and (v) theoretical models for coupled/single resonator bistable lasing structures.
