1Dual-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 2018Photonics Research2018,6,5:1
2Toward 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 2021Frontiers of Optoelectronics2021,14,4:0
3Dual-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 2022Frontiers of Optoelectronics2022,15,1:0
