1. Simultaneous all-channel OTDM demultiplexing based on complete optical Fourier transformation

Author

Guan, Pengyu, Lillieholm, Mads, Røge, Kasper Meldgaard, Morioka, Toshio, Oxenløwe, Leif Katsuo, Guan, Pengyu, Lillieholm, Mads, Røge, Kasper Meldgaard, Morioka, Toshio, and Oxenløwe, Leif Katsuo

Abstract

We demonstrate simultaneous OTDM demultiplexing of all 16-channels for 160-Gbit/s DPSK and 320-Gbit/s DQPSK signals based on complete OFT. Furthermore, numerical simulations show promising results for extending the proposed technique to spectrally efficient Nyquist-OTDM.

2. A Novel Phase Sensitive Amplifier Based QPSK Regenerator Without Active Phase-Locking

Author

Kjøller, Niels-Kristian, Da Ros, Francesco, Røge, Kasper Meldgaard, Guan, Pengyu, Galili, Michael, Oxenløwe, Leif Katsuo, Kjøller, Niels-Kristian, Da Ros, Francesco, Røge, Kasper Meldgaard, Guan, Pengyu, Galili, Michael, and Oxenløwe, Leif Katsuo

Abstract

We propose a novel QPSK regenerator scheme based on phase sensitive amplification of a pre-conditioned signal avoiding active phase-locking. Signal pre-conditioning is demonstrated experimentally with error-free (BER < 10-9) performance for a 10-Gbaud QPSK signal.

Abstract

We propose and demonstrate a novel PSK regenerator based on phase sensitive amplification without active phase-locking. The scheme is applied to regenerate a phase noise degraded 10-Gbit/s DPSK signal, improving receiver sensitivity by 3.5 dB.

4. All-optical ultra-high-speed OFDM to Nyquist-WDM conversion

Author

Abstract

We propose an all-optical ultra-high-speed OFDM to Nyquist-WDM conversion scheme based on complete OFT. An 8-subcarrier 640 Gbit/s DPSK OFDM super-channel is converted to eight 80-Gbit/s Nyquist-WDM channels with BER <10−9 performance for all channels.

Abstract

We propose a novel all-optical WDM regeneration scheme for DPSK signals based on optical Fourier transformation and phase sensitive amplification. Phase regeneration of a WDM signal consisting of 4x10-Gbit/s phase noise degraded DPSK channels is demonstrated for the first time.

6. Conversion of a DWDM signal to a single Nyquist channel based on a complete optical Fourier transformation

Abstract

We propose a DWDM-to-Nyquist channel conversion scheme based on complete Optical Fourier Transformation and optical Nyquist filtering. We demonstrate conversion from 50-GHz-grid 16×10 Gbit/s DPSK DWDM to a 160-Gbit/s Nyquist channel (0.9 symbol/s/Hz spectral efficiency) with 1.4 dB power penalty.

7. Real-time all-optical OFDM transmission system based on time-domain optical fourier transformation

Abstract

We propose a novel simple all-optical OFDM transmission system based on time-domain OFT using time-lenses. A real-time 160 Gbit/s DPSK OFDM transmission with 16 decorrelated data subcarriers is successfully demonstrated over 100 km.

Abstract

We demonstrate an AO-OFDM system with a WSS-based transmitter and time-lens based receiver for spectral magnification, achieving BER~10-9 for a 28×10 Gbit/s DPSK AO-OFDM signal. Furthermore, the receiver performance for DPSK and DQPSK is investigated using Monte Carlo simulations.
