A Hybrid Wavelength-polarization Labeling Scheme in Optical Packet Switching

摘要

An optical labeling scheme using hybrid multiwave-length-polarization (λP) label and amplitude shift keying (ASK) payload is introduced. This scheme exploits wavelengths with two different states of polarization (SOP), circular polarization state and linear polarization state, as label. Compared with multiwavelength labeling, it remarkably enlarges the header information and reduces the requirement of wavelength accuracy. An experiment system for generating and detecting the λP label, which is based on the difference of polarization extinction ratio (PER), is demonstrated. Theoretical analysis of signal and system performance is also discussed in detail.
