摘要： A biosensor for implementing an FP-WA coupled mode includes a dielectric layer and a metal layer. The dielectric layer includes a plurality of dielectric grooves, and the plurality of dielectric grooves are periodically distributed at equal intervals. An opening width of the dielectric groove gradually decreases in a direction from a groove opening to a groove bottom. The metal layer is disposed on the dielectric layer and includes metal grooves that are in one-to-one correspondence with the dielectric grooves.
