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
Thermally tunable silicon racetrack resonators with ultralow tuning power
Po Dong,Wei Qian,Hong Liang,Roshanak Shafiiha,Dazeng Feng,Guoliang Li,John E. Cunningham,Ashok V. Krishnamoorthy,Mehdi Asghari +8 more
TL;DR: The use of free-standing silicon racetrack resonators with undercut structures significantly enhances the tuning efficiency, with one order of magnitude improvement of that for previously demonstrated thermo-optic devices without undercuts.
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.
Journal ArticleDOI
High-speed Ge photodetector monolithically integrated with large cross-section silicon-on-insulator waveguide
Dazeng Feng,Shirong Liao,Po Dong,Ning-Ning Feng,Hong Liang,Dawei Zheng,Cheng-Chih Kung,Joan Fong,Roshanak Shafiiha,J. E. Cunningham,Ashok V. Krishnamoorthy,Mehdi Asghari +11 more
TL;DR: In this paper, a high speed Ge photodetector with a large cross-section silicon-on-insulate (SOI) waveguide is demonstrated, in which the Ge p-i-n junction is placed in the horizontal direction to enable very high speed operation.
