Tunable superconducting nanoinductors [PDF]
Nanotechnology, 2010 We characterize inductors fabricated from ultra-thin, approximately 100 nm wide strips of niobium (Nb) and niobium nitride (NbN). These nanowires have a large kinetic inductance in the superconducting state. The kinetic inductance scales linearly with the nanowire length, with a typical value of 1 nH/um for NbN and 44 pH/um for Nb at a temperature of 2.

Discrete, tunable color-entanglement [PDF]
CLEO/Europe - EQEC 2009 - European Conference on Lasers and Electro-Optics and the European Quantum Electronics Conference, 2009 Although frequency multiplexing of information has revolutionized the field of classical communications, the color degree of freedom (DOF) has been used relatively little for quantum applications. We experimentally demonstrate a new hybrid quantum gate that transfers polarization entanglement of non-degenerate photons onto the color DOF. We create, for

A passively Q-switched Ho:YVO4 Laser at 2.05 μm with Graphene Saturable Absorber
Applied Sciences, 2016 We report a passively Q-switched Ho:YVO4 laser pumped at 1.94 µm with multilayer graphene as a saturable absorber. At the absorbed pump power of 9.3 W, the maximum average output power of 2.2 W was obtained in Ho:YVO4 laser with minimum pulse width of ...

Gm-APD LiDAR Single-Source Data Self-Guided: Obtaining High-Resolution Depth Map
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 Geiger-mode avalanche photodiode (Gm-APD) array LiDAR has become the current research focus due to its sensitive response, high precision, and easy integration. However, due to the limitations of the fabrication process and manufacturing cost, the images

High-Efficiency Optical Parametric Oscillator Based on Stimulated Brillouin Scattering Pulse Shaping
IEEE Photonics Journal, 2019 We present an optical parametric oscillator (OPO) that uses a pump pulse shape tailored by stimulated Brillouin scattering. The theoretical analysis is carried out for comparison between Gaussian pump and the step function pulse pump.
