The invention relates to an implementation method for a
photonic crystal biochemical
sensor array capable of realizing parallel
perception. A
photonic crystal biochemical
sensor array is implemented on the same two-dimensional
photonic crystal flat module for the first time. A two-dimensional photonic
crystal-based flat structure is designed, and due to the design of a combination of resonant cavities with different resonant frequencies, high-efficiency
coupling between various resonant cavities and a photonic
crystal waveguide can be implemented, and the photonic
crystal biochemical
sensor array is designed. The array has a basic structure of a
triangular grid photonic crystal flat
structure based on an air hole, and mainly comprises a line defect photonic crystal
waveguide (W1
waveguide) and a plurality of resonant cavities with different resonant frequencies. In the scheme, five resonant cavities with different resonant frequencies are adopted, which are named H0-cavity-1, H0-cavity-2, H0-cavity-3, H0-cavity-4 and H0-cavity-5 respectively. Because high-efficiency
coupling between the various resonant cavities and the photonic crystal waveguide can be implemented, a
light field can be locally distributed in respective area through the various resonant cavities, and the capacity of parallelly sensing small-volume analyzed object is provided.
