Broadband nanoelectromechanical phase shifting of light on a chip
Menno Poot, Hong. X. Tang
We demonstrate an optomechanical phase shifter. By electrostatically deflecting the nanofabricated mechanical structure, the effective index of a nearby waveguide is changed and th…
Electrical tuning and switching of an optical frequency comb generated in aluminum nitride microring resonators
Hojoong Jung, King Y. Fong, Chi Xiong +1
Aluminum nitride has been shown to possess both strong Kerr nonlinearity and electro-optic Pockels effect. By combining these two effects, here we demonstrate on-chip reversible on…
Photonic Cavity Synchronization of Nanomechanical Oscillators
Mahmood Bagheri, Menno Poot, Linran Fan +2
Synchronization in oscillatory systems is a frequent natural phenomenon and is becoming an important concept in modern physics. Nanomechanical resonators are ideal systems for stud…
Optical frequency comb generation from aluminum nitride micro-ring resonator
Hojoong Jung, Chi Xiong, King Y. Fong +2
Aluminum nitride is an appealing nonlinear optical material for on-chip wavelength conversion. Here we report optical frequency comb generation from high quality factor aluminum ni…
Waveguide integrated low noise NbTiN nanowire single-photon detectors with milli-Hz dark count rate
Carsten Schuck, Wolfram H. P. Pernice, Hong X. Tang
Superconducting nanowire single-photon detectors are an ideal match for integrated quantum photonic circuits due to their high detection efficiency for telecom wavelength photons.…
Optical time domain reflectometry with low noise waveguide-coupled superconducting nanowire single-photon detectors
Carsten Schuck, Wolfram H. P. Pernice, Xiaosong Ma +1
We demonstrate optical time domain reflectometry over 200 km of optical fiber using low-noise NbTiN superconducting single-photon detectors integrated with Si3N4 waveguides. Our sm…
