TL;DR: In this paper, the impact of the modulator material on chirp, digital signal processing (DSP) algorithms and system-level performance in coherent digital optical links is analyzed.
Journal ArticleDOI
Compact single-etched sub-wavelength grating couplers for O-band application
Yun Wang,Luhua Xu,Amar Kumar,Yannick D'Mello,David Patel,Zhenping Xing,Rui Li,Ghulam Saber,Eslam El-Fiky,David V. Plant +9 more
TL;DR: Two single-etched sub-wavelength grating coupler designs for O-band application, one targeting at high coupling efficiency and the other targeting at broad operating bandwidth are demonstrated.
Journal ArticleDOI
Integrated polarisation handling devices
Ghulam Saber,Luhua Xu,Rakibul Hasan Sagor,Yun Wang,Amar Kumar,Deng Mao,Eslam El-Fiky,Eslam El-Fiky,David Patel,Alireza Samani,Zhenping Xing,Maxime Jacques,Yannick D'Mello,David V. Plant +13 more
TL;DR: In this paper, the authors provide an overview of the recent work on developing polarisation handling devices such as polarisation beam splitters and polarisers in indium phosphide and silicon-on-insulator platforms for optical communications and sensing applications.
Journal ArticleDOI
Fabry–Perot resonators with transverse coupling on SOI using loop mirrors
TL;DR: In this article, a transversely coupled Fabry-Perot resonator using loop mirrors as the end reflectors is demonstrated via simulations and experiments on the silicon-on-insulator (SOI) platform.
Journal ArticleDOI
Silicon-based optical links using novel direct detection, coherent detection and dual polarization methods for new generation transport architectures
Ghulam Saber,Gemma Vall-Llosera,David Patel,Alireza Samani,Rui Li,Mohamed Morsy-Osman,Mathieu Chagnon,Mathieu Chagnon,Eslam El-Fiky,Ramon Gutierrez-Castrejon,Ramon Gutierrez-Castrejon,Patryk Urban,Boris Dortschy,Fabio Cavaliere,Stephane Lessard,David V. Plant +15 more
TL;DR: The results suggest that, in the first access and aggregation segments of the network, integrated silicon-based modulators aided by PAM-4 modulation formats can support the stringent requirements of new generation transport networks in terms of speed, footprint and power consumption.
