Open AccessIn this Letter, an efficient bidirectional differential phase-shift keying (DPSK)-DPSK transmission for a ultradense wavelength division-multiplexed passive optical network is proposed. A single distributed feedback laser ...
First demonstration and field trial on multi-user UDWDM-PON full duplex PSK-PSK with single monolithic integrated dual-output-DFB-SOA based ONUs Chu, Guang Yong; Maho, Anaelle; Cano Valadez, Iván Nicolás; Polo Querol, Víctor; Brenot, Romain; Debregeas, Helene; Prat Gomà, Josep Joan (2016-10-15)
Open AccessWe demonstrate a monolithically integrated dual-output DFB-SOA, and conduct the field trial on a multi-user bidirectional coherent ultradense wavelength division multiplexing-passive optical network (UDWDM-PON). To the ...
Chu, Guang Yong (Universitat Politècnica de Catalunya, 2016-02-22)
Open AccessIt would be unaffordable if the WDM-PON technologies were directly applied for massive deployment. Hence, the potential WDM-PON is to be integrated and improved in order to adapt it for NGPON and the future 5G. The UDWDM-PON ...
Ultrafast wavelength jumping and wavelength adjustment with low current using monolithically integrated FML for long-reach UDWDM-PON Chu, Guang Yong; Prat Gomà, Josep Joan (2016-12-07)
Open AccessUltrafast wavelength jumping at optical network units (ONUs) for an access network with frequency modulated lasers (FMLs) is demonstrated. This FML consists of an intracavity tunable phase section and filtering gain section. ...
