Ultra-Low-Loss Silicon Nitride Photonics Based on Deposited Films Compatible with Foundries
Xingchen Ji, Yoshitomo Okawachi, Andres Gil-Molina +4
The fabrication processes of silicon nitride photonic devices used in foundries require low temperature deposition, which typically leads to high propagation losses. Here, we show…
Fabrication-Robust Silicon Photonic Devices in Standard Sub-Micron Silicon-on-Insulator Processes
Anthony Rizzo, Utsav Dave, Asher Novick +5
Perturbations to the effective refractive index from nanometer-scale fabrication variations in waveguide geometry plague high index-contrast photonic platforms including the ubiqui…
Measurements and modeling of atomic-scale sidewall roughness and losses in integrated photonic devices
Samantha Roberts, Xingchen Ji, Jaime Cardenas +2
Atomic-level imperfections play an increasingly critical role in nanophotonic device performance. However, it remains challenging to accurately characterize the sidewall roughness…
Integrated near-field thermo-photovoltaics for on-demand heat recycling
Gaurang R. Bhatt, Bo Zhao, Samantha Roberts +7
The energy transferred via thermal radiation between two surfaces separated by nanometers distances (near-field) can be much larger than the blackbody limit. However, realizing a r…
A Reconfigurable Nanophotonics Platform for Sub-Millisecond, Deep Brain Neural Stimulation
Aseema Mohanty, Qian Li, Mohammad Amin Tadayon +7
Nanophotonics provides the ability to rapidly and precisely reconfigure light beams on a compact platform. Infrared nanophotonic devices are widely used in data communications to o…
Resonance-Free Light Recycling
You-Chia Chang, Samantha P. Roberts, Brian Stern +1
The inability to efficiently tune the optical properties of waveguiding structures has been one of the major hurdles for the future scalability of integrated photonic systems. In s…
