Figure 1

Nanofibre Bragg cavities.

(a), Sketch of an NFBC. Note that the number of grating periods has been reduced. (b), SIM image of an NFBC (diameter 270 nm, groove depth 45 nm, pitch 300 nm and defect length 450 nm). Scalebar is 1 μm. (c), distribution of the electric field calculated using a 3D finite-difference time-domain (FDTD) algorithm. The black line indicates the cavity structure and the scalebar is 1 μm. (d), Transmission spectrum of the NFBC as obtained from the FDTD calculations.
