Abstract
A novel implementation of a variable beam splitter using a photonic crystal (PhC) is proposed. The beam splitter consists of two periodic structures: a non-channel dispersion guiding region and a band gap based splitting structure. The dispersion guiding PhC structure is used to route the optical wave by exploiting the dispersion properties of the lattice. Arbitrary power ratio between output beams can be achieved by varying the parameters of the splitting structure. Within the studied range of splitting structures, high output power was observed and verified experimentally.
