Novel Lens Design for Free-Space Optical Interconnects

摘要

The transposition of signals in space is fundamental to the optical interconnection of electronic systems. Previous free-space implementations employed a scheme based on imaging systems that are prone to aberrations. The system proposed here is useful for implementation of a three-stage Clos network, an optical transpose sector switch, a reconfigurable optical transpose system, and an optical cross connect switch. The purpose of this paper is to propose a non-imaging system for an optical transpose interconnect system, where a macrolens is inserted between the two mesolenses arrays, at the centre. The proposed macrolens is a Fourier transform lens system designed to be virtually aberration free.
