Lammers, Steven (author)Electron energy-loss spectroscopy (EELS) is a powerful analytical technique used in transmission electron microscopy (TEM) to investigate the energy loss of electrons as they interact with a specimen. EELS provides valuable information about the electronic structure, composition, and bonding properties of materials at the nanoscale. Despite its...master thesis 2024

Di Domenico, Giuseppe (author), Weisman, Dror (author), Panichella, A. (author), Roitman, Dolev (author), Arie, Ady (author)Spatial modes of light can be used as carriers of information in classical optical communication or as an alphabet in quantum optical communication. In order to exploit the spatial domain, it is required to (de)multiplex different modes from a shared input channel into different output ports. Mode sorters have been employed in free-space and...journal article 2022

Moody, Galan (author), Sorger, Volker J. (author), Blumenthal, Daniel J. (author), Juodawlkis, Paul W. (author), Loh, William (author), Jones, Alex E. (author), Pingault, B.J. (author), Elshaari, Ali W. (author), Zwiller, Val (author)Integrated photonics will play a key role in quantum systems as they grow from few-qubit prototypes to tens of thousands of qubits. The underlying optical quantum technologies can only be realized through the integration of these components onto quantum photonic integrated circuits (QPICs) with accompanying electronics. In the last decade,...journal article 2022

Ouyang, B. (author)Ultrasound sensors based on integrated photonics devices provide a new solution to meet the miniaturization demand for the detection functionality of transducers. An important example is the silicon ring-resonator (RR) ultrasound sensor developed in our department. This sensor combines a small footprint with high sensitivity and a low detection...doctoral thesis 2020

Ouyang, B. (author), Li, Yanlu (author), Kruidhof, Marten (author), Horsten, R.C. (author), Baets, Roel (author), van Dongen, K.W.A. (author), Caro-Schuurman, J. (author)We report a highly sensitive ultrasound sensor based on an integrated photonics silicon Mach-Zehnder interferometer (MZI). One arm of the MZI is located on a thin membrane, acting as the sensing part of the device. Ultrasound waves excite the membrane's vibrational mode, thus inducing modulation of the MZI transmission. The measured sensor...conference paper 2020

(author), Zwiller, V.G. (author)Single-photon sources and detectors are indispensable building blocks for integrated quantum photonics, a research field that is seeing ever increasing interest for numerous applications. In this work, we implemented essential components for a quantum key distribution transceiver on a single photonic chip. Plasmonic antennas on top of silicon...journal article 2019

(author), Wang, Tzu Jui (author), Huang, Kuo Chin (author), Yamashita, Yuichiro (author), Yaung, Dun Nian (author), Charbon-Iwasaki-Charbon, E. (author)We present a high-performance back-illuminated three-dimensional stacked single-photon avalanche diode (SPAD), which is implemented in 45-nm CMOS technology for the first time. The SPAD is based on a P<sup>+</sup>/Deep N-well junction with a circular shape, for which N-well is intentionally excluded to achieve a wide depletion region, thus...journal article 2018
