(Color online) (a) Optical and (b) TEM image of the sample (111) surface. (c) Angle-dependent reflection spectra of the sample. Inset: Peak position vs angle.
Reflection and transmission spectra of an absorbing and a nonabsorbing (PX) photonic crystal.
Strain-induced shifts in reflection (left) and transmission (right) of the absorbing photonic crystal, as the strain is increased from 0% to 2%, 4%, 8%, and 13%.
Strain sensitivity of the absorbing and nonabsorbing (PX) photonic crystals, defined as the fractional transmission change produced by a 1% increase in strain. The wavelength is normalized to the Bragg peak.
