Fig. 3

(A) SEM image of the bowtie photonic crystal. (B) Zoomed-in image of a single unit cell in the red box in (A). (C) Tilted SEM image of an undercut bowtie photonic crystal revealing the out-of-plane profile. (D) Measured transmission spectrum. The fundamental mode has Q ~ 100,000 at λ = 1578.85 nm. The second-order and third-order peaks are located at 1562.20 and 1546.96 nm, with Q factors of 21,800 and 5156, respectively. a.u., arbitrary units.
