Ultra-shallow junction electrodes in low-loss silicon micro-ring resonators
Bin-Bin Xu, Gabriele G. de Boo, Brett C. Johnson +8
Electrodes in close proximity to an active area of a device are required for sufficient electrical control. The integration of such electrodes into optical devices can be challengi…
Reconfigurable photonic RF filters based on integrated Kerr frequency comb sources
Xingyuan Xu, Mengxi Tan, Jiayang Wu +6
We demonstrate two categories of photonic radio frequency (RF) filters based on integrated optical micro-combs. The first one is based on the transversal filtering structure and th…
Reconfigurable fractional microwave signal processor based on a microcomb
Mengxi Tan, Xingyuan Xu, Jiayang Wu +6
We propose and demonstrate reconfigurable fractional microwave signal processing based on an integrated Kerr optical microcomb. We achieve two forms of microwave signal processing…
Grain refinement of stainless steel in ultrasound-assisted additive manufacturing
C. J. Todaro, M. A. Easton, D. Qiu +3
Metals and alloys fabricated by fusion-based additive manufacturing (AM), or 3D printing, undergo complex dynamics of melting and solidification, presenting challenges to the effec…
Comparison of different methods of nitrogen-vacancy layer formation in diamond for widefield quantum microscopy
A. J. Healey, A. Stacey, B. C. Johnson +5
Thin layers of near-surface nitrogen-vacancy (NV) defects in diamond substrates are the workhorse of NV-based widefield magnetic microscopy, which has applications in physics, geol…
Photonic RF channelizer based on a 90 wavelength optical soliton crystal 49GHz Kerr microcomb
Xingyuan Xu, Mengxi Tan, Jiayang Wu +7
We report a broadband radio frequency (RF) channelizer with up to 92 channels using a coherent microcomb source. A soliton crystal microcomb, generated by a 49 GHz micro-ring reson…
