Full-duplex WiFi Analog Transmission in RSOA-basedRadio-over-Fiber System with Wavelength-reuse

An Nguyen - Université Laval, Quebec, Canada Zhihui Cao - Université Laval, Quebec, Canada Kim Lefebvre - Université Laval, Quebec, Canada Leslie Rusch - Université Laval, Quebec, Canada

We experimentally demonstrate the transmission of full-duplex analog WiFi uplink and downlink at 10 MHz IF and 2.4 GHz RF, respectively. The BER is below FEC-threshold for 64QAM for transmissions of up to 20 km single mode fiber.

Impact of ONU Tuning Time in TWDM-PON with Dynamic Wavelength and Bandwidth Allocation: An FPGA-based Evaluation

Koteswararao Kondepu - Scuola Superiore Sant Anna, Pisa, Italy Luca Valcarenghi - Scuola Superiore Sant Anna, Pisa, Italy Dung Pham-Van - Scuola Superiore Sant Anna, Pisa, Italy Piero Castoldi - Scuola Superiore Sant Anna, Pisa, Italy

This experimental evaluation based on FPGAs shows that dynamic wavelength allocation in TWDM-PON reduces the average frame delay if the ratio between the ONU tuning time and the slot time is small.

Experimental demonstration of 51.56 Gbit/s PAM-4 at 900nm and impact of level dependent RIN

Sriharsha Kota-Pavan - Georgia Institute of Technology, Atlanta, Georgia, USA Justin Lavrencik - Georgia Institute of Technology, Atlanta, Georgia, USA Stephen Ralph - Georgia Institute of Technology, Atlanta, Georgia, USA

We demonstrate robust error-free transmission of 51.56 Gbit/s PAM-4 over multiple examples of 100m of OM4 and OM3 fiber with 900nm VCSELs.  Intensity dependent RIN is shown to improve performance prediction and impairment assessment.

Demonstration of Software-Defined Flexible-PON with Adaptive Data Rates between 13.8 Gb/s and 5.2 Gb/s Supporting Link Loss Budgets between 15 dB and 35 dB 

Lei Zhou - Huawei Technologies, Advance Optical Access Network Research Center, Shenzhen, China Naresh Chand - Huawei US R&D Center, New Jersey, USA Xiang Liu - Huawei US R&D Center, New Jersey, USA Guikai Peng - Huawei Technologies, Advance Optical Access Network Research Center, Shenzhen, China Huafeng Lin - Huawei Technologies, Advance Optical Access Network Research Center, Shenzhen, China Zebin Li - Huawei Technologies, Advance Optical Access Network Research Center, Shenzhen, China Zhenping Wang - Huawei Technologies, Advance Optical Access Network Research Center, Shenzhen, China Xiaofeng Zhang - Huawei Technologies, Advance Optical Access Network Research Center, Shenzhen, China Sam Wang - Huawei Technologies, Advance Optical Access Network Research Center, Shenzhen, China Frank Effenberger - Huawei US R&D Center, New Jersey, USA

We demonstrate a software-defined flexible-PON using 4-GSa/s DAC/ADC, IM/DD, adaptive bit-loading, and OFDM signal processing. We achieve adaptive data rates ranging between 13.8Gb/s and 5.2Gb/s with power loss budgets between 15dB and 35dB by using only 1.95GHz RF bandwidth.

Numerical Investigation into the Dynamics of Externally-Injected, Gain-Switched Lasers for Optical Comb Generation

Sean O Duill - The Rince Institute, School of Electronic Engineering, Dublin City University, Glasnevin, Dublin, Ireland Rui Zhou - The Rince Institute, School of Electronic Engineering, Dublin City University, Glasnevin, Dublin, Ireland Prince Anandarajah - The Rince Institute, School of Electronic Engineering, Dublin City University, Glasnevin, Dublin, Ireland Liam Barry - The Rince Institute, School of Electronic Engineering, Dublin City University, Glasnevin, Dublin, Ireland

We present simulation results of the nonlinear dynamics of externally-injected, gain-switched laser comb sources. We implement a fully-stochastic laser model and highlight the trade-off between the number of comb lines and the noise properties of the comb.

M-ary Phase Shift Keying Receiver Beating the Standard Quantum Limit for any Signal Power

Christian Mueller - Max Planck Institute for the Science of Light, Erlangen, Germany - Department of Physics, University of Erlangen-Nuremberg, Erlangen, Germany Andreas Leven - Bell Labs Germany - Alcatel-Lucent Deutschland AG, Stuttgart, Germany Henning Bülow - Bell Labs Germany - Alcatel-Lucent Deutschland AG, Stuttgart, Germany Laurent Schmalen - Bell Labs Germany - Alcatel-Lucent Deutschland AG, Stuttgart, Germany Gerd Leuchs - Max Planck Institute for the Science of Light, Erlangen, Germany - Department of Physics, University of Erlangen-Nuremberg, Erlangen, Germany Christoph Marquadt - Max Planck Institute for the Science of Light, Erlangen, Germany - Department of Physics, University of Erlangen-Nuremberg, Erlangen, Germany

We analyze a novel quantum receiver for M-ary phase-shift keyed signals that outperforms the standard quantum limit for any signal power. We provide a detailed analysis of its robustness against realistic imperfections and discuss the achievable mutual information.
