| Outline of Final Research Achievements |
Purpose of this research is to build the basic technology for the fabrication of new quantum information circuits using colloidal quantum dot (QD). We have studied wide range of technologies from device fabrication to QD synthesis. We fabricated photon emitter capable of on/off control of photon emission by micromachining action in combination with PbS QDs emitting at optical telecommunication wavelength. We succeeded to form a nano-sized hole on a silicon substrate and to locate QD inside. By focusing on three-dimensional structural symmetry, emission wavelength selectivity, high quantum efficiency, and uniformity control, we investigated synthetic methods, synthetic conditions, and silica coating of QD. Using ultra-short pulsed laser, we also succeeded in drawing optical waveguide in QD-mixed glass body.
