Toward integrated tantalum pentoxide optical parametric oscillators
Maximilian Timmerkamp, Niklas M. Lüpken, Shqiprim Adrian Abazi +3
We present a hybrid waveguide-fiber optical parametric oscillator (OPO) exploiting degenerate four-wave mixing in tantalum pentoxide. The OPO, pumped with ultrashort pulses at 1.55…
Inverse Design of Nanophotonic Devices using Dynamic Binarization
Marco Butz, Adrian S. Abazi, Rene Ross +2
The complexity of applications addressed with photonic integrated circuits is steadily rising and poses increasingly challenging demands on individual component functionality, perf…
Integrated GaN photonic circuits on silicon (100) for second harmonic generation
Chi Xiong, Wolfram Pernice, Kevin K. Ryu +4
We demonstrate second order optical nonlinearity in a silicon architecture through heterogeneous integration of single-crystalline gallium nitride (GaN) on silicon (100) substrates…
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…
NbTiN superconducting nanowire detectors for visible and telecom wavelengths single photon counting on Si3N4 photonic circuits
C. Schuck, W. H. P. Pernice, H. X. Tang
We demonstrate niobium titanium nitride superconducting nanowires patterned on stoichiometric silicon nitride waveguides for detecting visible and infrared photons. The use of sili…
