Optical characterization of deuterated silicon-rich nitride waveguides
Xavier X. Chia, George F. R. Chen, Yanmei Cao +3
Chemical vapor deposition-based growth techniques allow flexible design of CMOS-compatible materials. Here, we report the deuterated silicon-rich nitride films grown using plasma-e…
Microresonator Frequency Comb Based High-Speed Transmission of Intensity Modulated Direct Detection Data
Peng Xing, George F. R. Chen, Hongwei Gao +3
Globally, the long-haul transmission of ultra-high bandwidth data is enabled through coherent communications. Driven by the rapid pace of growth in interconnectivity over the last…
Bragg soliton compression and fission on a CMOS-compatible platform
Ezgi Sahin, Andrea Blanco-Redondo, Peng Xing +4
Higher-order soliton dynamics, specifically soliton compression and fission, underpin crucial applications in ultrafast optics, sensing, communications, and signal processing. Brag…
Highly Efficient Midinfrared On-Chip Electrical Generation of Graphene Plasmons by Inelastic Electron Tunneling Excitation
Kelvin J. A. Ooi, Hong Son Chu, Chang Yu Hsieh +2
Inelastic electron tunneling provides a low-energy pathway for the excitation of surface plasmons and light emission. We theoretically investigate tunnel junctions based on metals…
Efficiencies of Aloof-Scattered Electron Beam Excitation of Metal and Graphene Plasmons
Kelvin J. A. Ooi, Wee Shing Koh, Hong Son Chu +2
We assessed the efficiencies of surface plasmon excitation by an aloof-scattered electron beam on metals and graphene. Graphene is shown to exhibit high energy transfer efficiencie…
Waveguide engineering of graphene's nonlinearity
Kelvin J. A. Ooi, Lay Kee Ang, Dawn T. H. Tan
Graphene has recently been shown to possess giant nonlinearity; however, the utility of this nonlinearity is limited due to high losses and small interaction volume. We show that b…
