Abstract

In this paper, using the 2-D finite-difference time-domain (FDTD), we study a novel biosensor based on collimation effects in photonic crystals (PCs) with negative refractive index. Couplingk the collmated beam to a line of air holes (sensing region) filled with normal air, dry air, liquid and gas is thoroughly investigated. It is shown that by an appropriate selection of design paramters such as the air cylinder radii and coupling distance, it is possible to achieve ultracompact sensing platforms. The collimatin effect features channel allocation in nanosystems and high sensitivity for biomolecules sensing applications.
