(a) The calculated transmission spectra of a single-line defect PCWG (dashed lines) and a single-bent PCWG (solid line). (b) The comparison of the measured spectrum (black line) and simulated spectrum (gray line) of the doubly bent waveguides.

FIG. 3.

The measured transmission spectrum of the doubly bent waveguide with bending section length of (a) and (b) . (c) The transmission spectrum of (a) after numerically filtering the oscillations due to reflection of facets and the tunable laser. (d) The reflectance of the 60° photonic crystal bend extracted from the transmission spectrum in (c).

Image of FIG. 4.
FIG. 4.

(a) The reflectances calculated from the measured spectra with different values, 0.305(star-point line), 0.31(triangular-point-line), and 0.32(square-point line). The error bars represent the range of the reflectance extracted due to the range of propagation loss values from . (b) The simulated reflectance spectrum extracted from the transmission spectrum in Fig. 2(a).
