Abstract

Rapid reconfiguration of optical codes (OCs) can significantly enhance the confidentiality of coherent optical code division multiple access (OCDMA) system [1]. However, most of conventional OCDMA encoding/decoding schemes do not have this capability. Recently, a fast reconfigurable time domain spectral phase encoding (SPE) scheme, which has this capability, has been proposed using high speed phase modulator and arrayed waveguide grating (AWG) decoder [2]. In this paper, we propose a novel synchronous time-domain spectral phase encoding/decoding (SPED) scheme for secured optical communication.
