A photonic switching system is expected to have advantages over a conventional electronic switching system in exchanging broadband signals. Extensive studies have recently done on various photonic switching systems. State-of-art technology in photonic switching systems is surveyed in this paper. Small-capacity space-division switching systems using waveguide optical matrix switches are most practical and expected to be introduced to broadband local-area network in the near future. Wavelength division switching technology is important in extending switching capacity to large value. Application of photonic switching technology for ATM switching systems is also recently extensively studied to achieve switching throughput larger than that of electronic ATM switches.
