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
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.
Journal ArticleDOI
High speed carrier-depletion modulators with 1.4V-cm V(pi)L integrated on 0.25microm silicon-on-insulator waveguides.
Ning-Ning Feng,Shirong Liao,Dazeng Feng,Po Dong,Dawei Zheng,Hong Liang,Roshanak Shafiiha,Guoliang Li,John E. Cunningham,Ashok V. Krishnamoorthy,Mehdi Asghari +10 more
TL;DR: A very efficient high speed silicon modulator with an ultralow pi-phase-shift voltage-length product V(pi)L = 1.4V-cm is demonstrated, achieved through the optimization of the overlap region of carriers and photons.
Journal ArticleDOI
Low loss shallow-ridge silicon waveguides.
Po Dong,Wei Qian,Shirong Liao,Hong Liang,Cheng-Chih Kung,Ning-Ning Feng,Roshanak Shafiiha,Joan Fong,Dazeng Feng,Ashok V. Krishnamoorthy,Mehdi Asghari +10 more
TL;DR: Low loss shallow-ridge silicon waveguides with an average propagation loss of 0.274 + or - 0.008 dB/cm in the C-band are demonstrated and a compact double-level taper is investigated which adiabatically couples light from these waveguiding to silicon strip waveguide enabling tight bends.
