Fabrication Technologies of Quantum Dots

Home > Research Subjects > Fabrication Technologies of Quantum Dots
We establish device technologies for high-speed quantum dot lasers (>40GHz) with low spectral chirping, as well as ultralow threshold photonic crystal lasers in which electron-photon interaction is precisely controlled. Furthermore, single photon emitters and single electronics are explored for application to quantum cryptography communication and quantum computing devices.
