Figure 1

Schematic diagram of a 7.5 period, 1D, PhC with triple LC defects. The defects are realised in the second, fourth, and sixth periods (denoted by numbers). A Si wall thickness with fluctuation ± δ dSi in each lattice period causes a variation of groove thickness d air = a d Si ± δ d Si . The lattice constant is a = d Si + d air . The optical contrast of the defect-free PhC is nSi/nair.
