The principle and design of a self-routing 16 X 16 free-space optically interconnected crossbar cell switch are detailed. Vertical cavity surface emitting lasers (VCSELs) and VCSEL-based smart pixel arrays are key devices for this system and enable high density interconnection. Using the optical switching of VCSEL polarization extensively, the cell switch exhibits a potential high bit rate and low reconfiguration time between two cells. Moreover, because of the high speed switching of the VCSEL between its two linear polarizations, address substitution, which is one of the asynchronous transfer mode (ATM) requirements, can be implemented. A compact cell-switch demonstrator is proposed that uses low-cost optically recorded holograms and microlens arrays.
