A universal 3D imaging sensor on a silicon photonics platform
Christopher Rogers, Alexander Y. Piggott, David J. Thomson +9
Accurate 3D imaging is essential for machines to map and interact with the physical world. While numerous 3D imaging technologies exist, each addressing niche applications with var…
SU-8 clamped CVD graphene drum resonators
Sunwoo Lee, Changyao Chen, Vikram V. Deshpande +8
Graphene mechanical resonators are the ultimate two-dimensional nanoelectromechanical systems (NEMS) with applications in sensing and signal processing. While initial devices have…
Modulation of mechanical resonance by chemical potential oscillation in graphene
Changyao Chen, Vikram V. Deshpande, Mikito Koshino +5
The classical picture of the force on a capacitor assumes a large density of electronic states, such that the electrochemical potential of charges added to the capacitor is given b…
Graphene Metallization of High-Stress Silicon Nitride Resonators for Electrical Integration
Sunwoo Lee, Vivekananda P. Adiga, Robert A. Barton +7
High stress stoichiometric silicon nitride resonators, whose quality factors exceed one million, have shown promise for applications in sensing and signal processing. Yet, electric…
Radio frequency electrical transduction of graphene mechanical resonators
Yuehang Xu, Changyao Chen, Vikram V. Deshpande +6
We report radio frequency (rf) electrical readout of graphene mechanical resonators. The mechanical motion is actuated and detected directly by using a vector network analyzer, emp…
Stimulated emission in erbium doped silicon rich nitride waveguides
Debo Olaosebikan, Selcuk Yerci, Alexander Gondarenko +4
Stimulated emission of sensitized Erbium atoms is reported in silicon-rich silicon nitride waveguides. Visible pump and infrared probe measurements are carried out in waveguides fa…
Monolithically integrated multiple wavelength oscillator on silicon
Jacob S. Levy, Alexander Gondarenko, Mark A. Foster +3
Silicon photonics enables on-chip ultra-high bandwidth optical communications networks which is critical for the future of microelectronics1,2. By encoding information on-chip usin…
Controlling photonic structures using optical forces
Gustavo S. Wiederhecker, Long Chen, Alexander Gondarenko +1
The downscaling of optical systems to the micro and nano-scale results in very compliant systems with nanogram-scale masses, which renders them susceptible to optical forces. Here…
