Journal ArticleDOI
Design, analysis, and transmission system performance of a 41 GHz silicon photonic modulator.
David Patel,Samir Ghosh,Mathieu Chagnon,Alireza Samani,Venkat Veerasubramanian,Mohamed Osman,David V. Plant +6 more
TL;DR: With the use of multi-level amplitude modulation formats and digital-signal-processing, the modulator is shown to operate below a hard-decision forward error-correction threshold of 3.8×10-3 at bitrates up to 112 Gbps over 2 km of single mode optical fiber using PAM-4, and over 5 km of optical fiber with PAM -8.
Journal ArticleDOI
Optimization of thermo-optic phase-shifter design and mitigation of thermal crosstalk on the SOI platform.
TL;DR: Doped-Si-based heaters are the most practical and efficient on standard SOI and the layout density of highly integrated dies is optimized, and internal and external thermal crosstalk for tunable Mach-Zehnder interferometers is experimentally characterized.
Journal ArticleDOI
A Low-Voltage 35-GHz Silicon Photonic Modulator-Enabled 112-Gb/s Transmission System
Alireza Samani,Mathieu Chagnon,David Patel,Venkat Veerasubramanian,Samir Ghosh,Mohamed Osman,Qiuhang Zhong,David V. Plant +7 more
TL;DR: In this article, a silicon photonic traveling-wave Mach-Zehnder modulator operating near 1550 nm with a 3-dB bandwidth of 35 GHz was presented, and the performance of the device in short-reach transmission system was investigated.
Journal ArticleDOI
Focusing-curved subwavelength grating couplers for ultra-broadband silicon photonics optical interfaces
Qiuhang Zhong,Venkat Veerasubramanian,Yun Wang,Wei Shi,David Patel,Samir Ghosh,Alireza Samani,Lukas Chrostowski,Richard Bojko,David V. Plant +9 more
TL;DR: With implementation of waveguide dispersion engineered subwavelength structures, an ultra-wide 1-dB bandwidth of over 100 nm (largest reported to date) near 1550 nm is experimentally achieved for transverse-electric polarized light.
Journal ArticleDOI
Silicon Photonic Segmented Modulator-Based Electro-Optic DAC for 100 Gb/s PAM-4 Generation
TL;DR: In this article, a traveling-wave multi-electrode Mach-Zehnder modulator (MZM) was developed to achieve a 4-level pulse amplitude modulation (PAM) signal at speeds up to 50 GBd.
