Abstract
The invention discloses an N-port block-free optical router based on Mach-Zehnder switches. Two optical waveguides and 2(N-2) Mach-Zehnder switches with the same structure and size are added into an (N-2)-port block-free optical router structure to expand the number of ports from N-2 to N. The block-free optical router with the number of the ports as an odd number can be achieved by expanding a three-port block-free router step by step. The block-free optical router with the number of the ports as an even number can be achieved by expanding a four-port block-free router step by step. The phase of the Mach-Zehnder switches corresponding to a modulation arm can be modulated to enable the Mach-Zehnder switches to be dynamically switched to be in two states and further achieve block-free communication between N bidirectional ports of the optical router. The N-port block-free optical router solves the problem that the number of ports of an existing router cannot be expanded at will.
