摘      要：A novel optical beam splitter constructed on the basis of photonic crystal（PC） with hybrid lattices is proposed in this *** band gap of square-lattice PC is so designed that the incident light is divided into several branch ***-lattice graded-index PCs are combined for focusing each *** calculations are carried out on the basis of finite-different time-domain algorithm to prove the feasibility of our *** waveguide is unnecessary in the *** the device has functions of both splitting and focusing *** of the divided beam at site of full-width at half-maximum is of the order of λ/*** designed splitter has the advantages that it has a small volume and can be integrated by conventional semiconductor manufacturing process
