“…OLS recently attracts much attention and many schemes of OLS have been proposed, which are summarized and compared in 3 . Among these OLS methods, orthogonal modulation is widely applied 4‐13 . Orthogonal modulation superimposes a nonamplitude‐modulated signal on an amplitude shift keying (ASK) signal.…”

“…The nonamplitude modulation applied in OLS includes frequency shift keying (FSK), 4,5 differential phase shift keying (DPSK) 6‐12 and polarization shift keying (PolSK) 13 . As PolSK is sensitive to the polarization rotation and FSK occupies more wavelength resource and suffers more dispersion, DPSK is mostly applied among the three modulations.…”

Optical label switching (OLS) is a promising solution for rapidly growing packet based internet traffic and data switching in data center. Most proposed schemes apply orthogonal modulation, which superimpose a nonamplitude modulated label signal onto a Manchester coded or pulse position modulated (PPM) ASK payload signal. The extinction ratio (ER) has to be reduced for overlaid signal. To avoid the quality degradation of payload signal from low ER, a differential phase shift keying (DPSK) over inverse PPM is proposed in this paper. Due to the high mark ratio of the inverse PPM, the proposed DPSK over inverse PPM modulation achieves a high ER for the ASK signal while induces limited crosstalk to the DPSK signal. Compare with the previously proposed schemes, the test results show the proposed DPSK over inverse 4PPM modulation achieves an optimum ER improvement of at least 6 dB to support an extended of at least 10.5 km.

“…Recently, an all-optical sampling (AOS) OFDM system using ultra-short pulses as optical samples introduced cyclic postfix (CP) to improve fiber dispersion tolerance [9] . However, different system configurations will influence the performance significantly, such as the number of channels, the data modulation format [10,11] , and the sample pulse width.…”

The performance of a novel all-optical sampling orthogonal frequency division multiplexing (OFDM) system is proposed and analyzed. Time delays and phase shifters are used to realize all optical forward/inverse discrete Fourier transform (DFT/IDFT). Different system configurations are tested and analyzed to optimize the performance, including the system capacity, modulation formats, DFT/IDFT constructions, and the width of the sample pulse. The 50-and 100-Gb/s real-time all-optical sampling (AOS) OFDM systems are investigated. All results are analyzed, and useful suggestions are offered for future high-speed applications.
