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 <a onClick="popup('http://www.nanoscalereslett.com/content/7/1/387/mathml/M2','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/7/1/387/mathml/M2">View MathML</a>. The lattice constant is <a onClick="popup('http://www.nanoscalereslett.com/content/7/1/387/mathml/M3','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/7/1/387/mathml/M3">View MathML</a>. The optical contrast of the defect-free PhC is nSi/nair.
