Abstract We introduce a photonic crystal cavity array realised in a silicon thin film and placed on polydimethlysiloxane PDMS as a new platform for the in-situ sensing of biomedical processes. Using tapered optical fibres, we show that multiple independent cavities within the same waveguide can be excited and their resonance wavelength determined from camera images without the need for a spectrometer. The cavity array platform combines sensing as a function of location with sensing as a function of time. View Full-Text
