Coherent Access: A Review
Ali Shahpari,Ricardo B. Ferreira,Ruben S. Luis,Zoran Vujicic,Fernando P. Guiomar,Jacklyn D. Reis,Antônio Lúcio Teixeira +6 more
TL;DR: In this paper, a set of architectures for coherent optical access networks is presented and the key attributes of each scenario are investigated, as a basis to decrease the cost of the local oscillator (LO) at customer side, and the possibility of using a low-cost laser as LO with real-time detection of a Nyquist-shaped differential quadrature phase-shift keying (DQPSK) signal using simple 8-bit digital signal processing (DSP) on a fieldprogrammable gate array.
Journal ArticleDOI
Ultra High Capacity Self-Homodyne PON With Simplified ONU and Burst-Mode Upstream
Ruben S. Luis,Ali Shahpari,Jacklyn D. Reis,Ricardo B. Ferreira,Zoran Vujicic,Benjamin J. Puttnam,Jose Manuel Delgado Mendinueta,Mário Lima,Moriya Nakamura,Yukiyoshi Kamio,Naoya Wada,Antônio Lúcio Teixeira +11 more
TL;DR: In this article, the authors demonstrate a proof of concept fully loaded bidirectional ultrahigh capacity coherent passive optical network (2 × 1008 × 8.3 Gb/s) using partial spectrum overlap, Nyquist shaping, digital frequency shifting, self-homodyne detection, and pilot tone remodulation.
Journal ArticleDOI
Coherent ultra dense wavelength division multiplexing passive optical networks
Ali Shahpari,Ricardo B. Ferreira,Vitor Ribeiro,Artur Sousa,Somayeh Ziaie,Ana Tavares,Zoran Vujicic,Fernando P. Guiomar,Jacklyn D. Reis,Armando N. Pinto,Antônio Lúcio Teixeira +10 more
TL;DR: In this paper, the progress in ultra-dense wavelength division multiplexing passive optical network (UDWDM-PON) is reviewed by making use of the key attributes of this technology in the context of optical access and metro networks.
Journal ArticleDOI
Efficient Dynamic Modeling of the Reflective Semiconductor Optical Amplifier
TL;DR: A time-domain wideband model is presented for simulation of spatial and temporal distribution of photons and carriers in a bulk RSOA and a novel approach for efficient amplified spontaneous emission modeling is provided, considering a tradeoff between the accuracy and the computational efficiency.
Journal ArticleDOI
Self-Homodyne Detection-Based Fully Coherent Reflective PON Using RSOA and Simplified DSP
Zoran Vujicic,Ruben S. Luis,Jose Manuel Delgado Mendinueta,Ali Shahpari,Natasa B. Pavlovic,Benjamin J. Puttnam,Yukiyoshi Kamio,Moriya Nakamura,Naoya Wada,Antônio Lúcio Teixeira +9 more
TL;DR: In this article, the authors investigate the power budget of a fully coherent reflective passive optical network, based on self-coherent upstream (US) and self-homodyne downstream (DS) detection schemes.
