| 1 | Dual-polarization wavelength conversion of 16-QAM signals in a single silicon waveguide with a lateral p-i-n diode[Invited]显示文摘A polarization-diversity loop with a silicon waveguide with a lateral p-i-n diode as a nonlinear medium is used to realize polarization insensitive four-wave mixing. Wavelength conversion of seven dual-polarization 16-quadrature amplitude modulation(QAM) signals at 16 GBd is demonstrated with an optical signal-to-noise ratio penalty below 0.7 dB. High-quality converted signals are generated thanks to the low polarization dependence(≤0.5 dB) and the high conversion efficiency(CE) achievable. The strong Kerr nonlinearity in silicon and the decrease of detrimental free-carrier absorption due to the reverse-biased p-i-n diode are key in ensuring high CE levels. | FRANCESCO DA Ros ANDRZEJ GAJDA ERIK LIEBIG EDSON P.DA SILVA ANNA PECZEK PETER D.GIROUARD ANDREAS MAI KLAUS PETERMANN LARS ZIMMERMANN MICHAEL GALILI LEIF K.OXENLOWE | 2018 | Photonics Research2018，6，5： | 1 |

| 3 | Single-chip Si optical single-sideband modulator显示文摘We demonstrate an integrated Si optical single-sideband(OSSB) modulator composed of a parallel dual-ring modulator(PDRM) and a quadrature hybrid coupler(QHC). Both the PDRM and the QHC are carefully designed for 30 GHz opearation, and their operations are verified by measurement. The Si OSSB modulator successfully generates a single sideband with larger than 15 dB suppression of the undesired sideband. | BYUNG-MIN Yu JEONG-MIN LEE CHRISTIAN MAI STEFAN LISCHKE LARS ZIMMERMANN AND Woo-YOUNG CHOI | 2018 | Photonics Research2018，9，1： | 1 |

| 6 | Influence of dynamic power dissipation on Si MRM modulation characteristics显示文摘We experimentally observe that Si micro-ring modulator(MRM) modulation characteristics are strongly influenced by the modulation data rate and the data pattern and determine this influence is due to the temperature increase caused by dynamic power dissipation within the Si MRM device. We also quantitatively determine the amount of Si MRM resonance wavelength shift due to different modulation data rates, data patterns, and modulation voltages. Our results should be of great help for achieving reliable and optimal modulation characteristics for Si MRMs. | Byung-Min Yu Myungjin Shin Min-Hyeong Kim Lars Zimmermann Woo-Young Choi | 2017 | Chinese Optics Letters2017，15，7： | 0 |
| 7 | Toward coherent O-band data center interconnects显示文摘Upcoming generations of coherent intra/inter data center interconnects currently lack a clear path toward a reduction of cost and power consumption,which are the driving factors for these data links.In this work,the tradeoffs associated with a transition from coherent C-band to O-band silicon photonics are addressed and evaluated.The discussion includes the fundamental components of coherent data links,namely the optical components,fiber link and transceivers.As a major component of these links,a monolithic silicon photonic BiCMOS O-band coherent receiver is evaluated for its potential performance and compared to an analogous C-band device. | Pascal M.SEILER Galina GEORGIEVA Georg WINZER Anna PECZEK Karsten VOIGT Stefan LISCHKE Adel FATEMI Lars ZIMMERMANN | 2021 | Frontiers of Optoelectronics2021，14，4： | 0 |

| 9 | Dual-polarization multiplexing amorphous Si:H grating couplers for silicon photonic transmitters in the photonic BiCMOS backend of line显示文摘In this paper,we report on polarization combining two-dimensional grating couplers(2D GCs)on amorphous Si:H,fabricated in the backend of line of a photonic BiCMOS platform.The 2D GCs can be used as an interface of a hybrid silicon photonic coherent transmitter,which can be implemented on bulk Si wafers.The fabricated 2D GCs operate in the telecom C-band and show an experimental coupling efficiency of−5 dB with a wafer variation of±1.2 dB.Possibilities for efficiency enhancement and improved performance stability in future design generations are outlined and extension toward O-band devices is also investigated. | Galina Georgieva Christian Mai Pascal M.Seiler Anna Peczek Lars Zimmermann | 2022 | Frontiers of Optoelectronics2022，15，1： | 0 |
| 10 | Large-signal SPICE model for depletion-type silicon ring modulators显示文摘We present an accurate, easy-to-use large-signal SPICE circuit model for depletion-type silicon ring modulators(Si RMs). Our model includes both the electrical and optical characteristics of the Si RM and consists of circuit elements whose values change depending on modulation voltages. The accuracy of our model is confirmed by comparing the SPICE simulation results of 25 Gb/s non-return-to-zero(NRZ) modulation with the measurement. The model is used for performance optimization of monolithically integrated Si photonic NRZ and pulse-amplitudemodulation 4 transmitters in the standard SPICE circuit design environment. | MINKYU KIM MYUNGJIN SHIN MIN-HYEONG KIM BYUNG-MIN YU YOUNGHYUN KIM YOOJIN BAN STEFAN LISCHKE CHRISTIAN MAI LARS ZIMMERMANN WOO-YOUNG CHOI | 2019 | Photonics Research2019，7，9： | 0 |
