Systems And Methods For Suspended Polymer Photonic Crystal Cavities And Waveguides

摘要

Systems and methods for suspended polymer photonic crystal (SPPC) cavities and waveguides are disclosed. In one aspect, photonic crystal cavities are provided. An exemplary photonic crystal cavity can include a substrate having a trench. A polymer film can be suspended above the trench thereby forming a gap between the polymer film and the substrate. The polymer film can include a plurality of holes to thereby form at least one optical cavity. The plurality of holes can have a lattice spacing, and each hole can have a radius. The radius and lattice spacing of the plurality of holes can be adapted to increase a gap-midgap ratio. In another aspect, photonic waveguides are provided. In another, methods for fabricating an SPPC are provided. In another, methods for sensing using a polymer photonic crystal ladder cavity are disclosed. In another, methods for optical filtering using an SPPC waveguide-coupled cavity drop filter are disclosed.

1. A photonic crystal cavity, comprising:
a substrate having a trench on at least one surface; and a polymer film suspended above the trench thereby forming a gap between at least a portion of the polymer film and the substrate, the polymer film including a plurality of holes to thereby form at least one optical cavity, the plurality of holes having a lattice spacing, each of the plurality of holes having a radius, wherein the radius and the lattice spacing of the plurality of holes are adapted to increase a gap-midgap ratio.
