Interference between single photons lies at the heart of linear optical quantum computing (LOQC). However, the lack of deterministic single photon sources hinders the large-scale experimental demonstration and its practical applications, as the probability to generate N single photons simultaneously (denoted by N-photon hereafter) decreases exponentially with the increasing number of single photon...
We demonstrate heralded single photon source on a silicon photonic chip by a pump interleaving technique. We have achieved 90±5% enhancement to single photon rate with only 14±2% reduction in quantum signal to noise ratio.
We identify three regimes of correlated GeV-electron/keV-betatron-x-ray generation by a laser-plasma accelerator driven by the Texas Petawatt laser, and relate them to variations in strength of blowout, injection geometry and beam loading.
A 20nm thick Ni resistor element was fabricated on a 1µm thick, 400µm wide silicon nitride bridge via bulk micromachining. By applying a given power to the resistor its temperature increases, as the pressure decreases, since fewer gas particles are available to transfer heat away from the resistor. Rather than sensing the resistance change, a thin film thermocouple consisting of 20nm Ni and 20nm Cr...

This paper presents a novel MEMS configuration for three dimensional on-chip fine positioning and mechanical fixing of a ball lens. A MEMS lens holder, which consists of a suspended mass, is attached onto a MEMS active alignment platform to achieve precision alignment and fixing of a ball lens with a diameter of 300µm in silicon photonics packaging. The operational principles of the system as well...
Based on a hybrid-plasmon (HPP) platform, we report the first demonstrations of low-loss, deep-subwavelength waveguiding and plasmon semiconductor Nanolaser with room temperature operating, towards wavelength-scale photonic integrated circuits.

This paper reports a novel silicon platform with integrated MEMS actuators, which is used for fine-positioning and locking of a ball-lens, to address the optical coupling issues in silicon photonics packaging. The fine-positioning and locking function of the ball-lens have been successfully demonstrated by the developed prototype silicon platform. The main adjusting actuator delivered a large force...
We demonstrate that using longer-wavelength driving light in high-order harmonic generation requires moderately ionized larger-density atoms to perfectly phase match the process, scaling conventional phase matching at low ionization to extremely high photon energies.
