Journal ArticleDOI
Computer Systems Based on Silicon Photonic Interconnects
Ashok V. Krishnamoorthy,Ron Ho,Xuezhe Zheng,Herbert D. Schwetman,Jon Lexau,Pranay Koka,Guoliang Li,Ivan Shubin,John Cunningham +8 more
TL;DR: The power dissipation of a photonic link is explored, a roadmap to lower the energy-per-bit of silicon photonic interconnects is suggested, and the challenges that will be faced by device and circuit designers towards this goal are identified.
Journal ArticleDOI
Low V_pp, ultralow-energy, compact, high-speed silicon electro-optic modulator
Po Dong,Shirong Liao,Dazeng Feng,Hong Liang,Dawei Zheng,Roshanak Shafiiha,Cheng-Chih Kung,Wei Qian,Guoliang Li,Xuezhe Zheng,Ashok V. Krishnamoorthy,Mehdi Asghari +11 more
TL;DR: A high-speed silicon optical modulator with a low V(pp) (peak-to-peak driving voltage) and ultralow energy consumption based on a microring resonator, with the refractive index modulation achieved by electric-field-induced carrier depletion in a reverse-biased lateral pn diode embedded in the ring structure.
Journal ArticleDOI
25Gb/s 1V-driving CMOS ring modulator with integrated thermal tuning
Guoliang Li,Xuezhe Zheng,Jin Yao,Hiren D. Thacker,Ivan Shubin,Ying Luo,Kannan Raj,John E. Cunningham,Ashok V. Krishnamoorthy +8 more
TL;DR: A high-speed ring modulator that fits many of the ideal qualities for optical interconnect in future exascale supercomputers and fits in a compact 400 μm2 footprint is reported.
Journal ArticleDOI
Low power and compact reconfigurable multiplexing devices based on silicon microring resonators
Po Dong,Wei Qian,Hong Liang,Roshanak Shafiiha,Ning-Ning Feng,Dazeng Feng,Xuezhe Zheng,Ashok V. Krishnamoorthy,Mehdi Asghari +8 more
TL;DR: It is shown that thermally reconfigurable multiplexing devices based on silicon microring resonators with low tuning power and low thermal crosstalk can be implemented in a compact manner by exploiting thermal isolation trenches close to the ring waveguides.
Journal ArticleDOI
Wavelength-tunable silicon microring modulator.
Po Dong,Roshanak Shafiiha,Shirong Liao,Hong Liang,Ning-Ning Feng,Dazeng Feng,Guoliang Li,Xuezhe Zheng,Ashok V. Krishnamoorthy,Mehdi Asghari +9 more
TL;DR: This device aims to solve the narrow bandwidth problem of silicon microcavity modulators and increase the data bandwidth in optical interconnect systems.
