Fabrication and nonlinear measurements of high- Q defect-free optical nanofiber photonic crystal resonators
Abstract
We demonstrate the fabrication of defect-free optical-nanofiber photonic-crystal Fabry-Pérot resonators with quality factors exceeding 10 7 using single-shot femtosecond laser ablation. An investigation of the nonlinear optical properties reveals that thermo-optic effects dominate within the entire cavity bandwidth, even when interrogating with pulses one order of magnitude shorter than the 6.6 µ s thermal cutoff time. The combination of high- Q and small mode volume of these resonators could facilitate the creation of high-speed quantum nodes for cavity QED based quantum computing and networking, as well as low-power in-line fiber optical switches.
