| Outline of Final Research Achievements |
In this research program, the applicant developed a completely new method of achieving "photonic crystal cavities" on a nano-waveguide. The method combined a nano-fabricated silica grating containing a central "defect" with an optical "nanofiber" (sub-wavelength diameter optical fiber). By mounting the grating on the optical nanofiber, we achieved a small mode-volume cavity for light guided inside the nanofiber. When quantum emitters are placed on the nanofiber surface, the experience a strong enhancement of spontaneous emission at the cavity resonance wavelength, making the device promising technology for the realization of narrow-band, fiber coupled single photon sources.
Before manufacturing the device, we designed the grating using computer simulations. Finally, we realized cavity QED based enhancement for a quantum dot deposited on the nanofiber surface by using the composite photonic crystal cavity technique.
