Ridge Resonance: A new Resonance Phenomenon for Silicon Photonics Harnessing Bound States in the Continuum
Thach G. Nguyen, Guanghui Ren, Steffen Schoenhardt +3
We present a new resonant behavior based on bound states in the continuum in a guided wave silicon platform. The continuum has the form of a collimated beam of light which is confi…
Tunable RF and microwave photonic sideband generator based on cascaded 49GHz and 200GHz integrated ring resonators
Xingyuan Xu, Jiayang Wu, Linnan Jia +7
We demonstrate a continuously RF tunable orthogonally polarized optical single sideband (OP-OSSB) generator based on dual cascaded micro-ring resonators. By splitting the input dou…
On-chip correlation-based Brillouin sensing: design, experiment and simulation
Atiyeh Zarifi, Birgit Stiller, Moritz Merklein +10
Wavelength-scale SBS waveguides are enabling novel on-chip functionalities. The micro- and nano-scale SBS structures and the complexity of the SBS waveguides require a characteriza…
Photonic single sideband RF generator based on an integrated optical micro-ring resonator
Xingyuan Xu, Jiayang Wu, Mengxi Tan +6
We demonstrate narrowband orthogonally polarized optical RF single sideband generation as well as dual-channel equalization based on an integrated dual-polarization-mode high-Q mic…
Brillouin spectroscopy of a hybrid silicon-chalcogenide waveguide with geometrical variations
Atiyeh Zarifi, Birgit Stiller, Moritz Merklein +10
Recent advances in design and fabrication of photonic-phononic waveguides have enabled stimulated Brillouin scattering (SBS) in silicon-based platforms, such as under-etched silico…
A Radio Frequency Channelizer based on Cascaded Integrated Micro-ring Resonator Optical Comb Sources and Filters
Xingyuan Xu, Jiayang Wu, Thach G. Nguyen +5
We report a broadband RF channelizer based on an integrated optical frequency Kerr micro-comb source, with an RF channelizing bandwidth of 90 GHz, a high RF spectral slice resoluti…
Photonic RF and microwave reconfigurable filters and true time delays based on an integrated optical Kerr frequency comb source
Xingyuan Xu, Jiayang Wu, Thach G. Nguyen +6
We demonstrate advanced transversal radio frequency (RF) and microwave functions based on a Kerr optical comb source generated by an integrated micro-ring resonator. We achieve ext…
