Abstract :
Properties of non-freestanding silicon slot photonic crystal cavities for application to sensing are investigated by probing their resonance wavelength tuning as a function of covering material index. Sensitivities of 225 nm/RIU are obtained with Q around 30,000 and cavity mode volumes ~ V=0.03(λ/n)3.
