The GEO 600 laser system [PDF]

open access: yes, 2002
Interferometric gravitational wave detectors require high optical power, single frequency lasers with very good beam quality and high amplitude and frequency stability as well as high long-term reliability as input light source.

Polynomial Solution of Non-Central Potentials [PDF]

open access: yes, 2007
We show that the exact energy eigenvalues and eigenfunctions of the Schrodinger equation for charged particles moving in certain class of non-central potentials can be easily calculated analytically in a simple and elegant manner by using Nikiforov and ...

Quantum ring models and action-angle variables

open access: yes, 2010
We suggest to use the action-angle variables for the study of properties of (quasi)particles in quantum rings. For this purpose we present the action-angle variables for three two-dimensional singular oscillator systems.

Photonic microwave harmonic generator driven by an optoelectronic ring oscillator [PDF]

open access: yes, 2007
We describe a new architecture to generate microwave signals by optical means. Our system combines the advantages of two techniques: frequency multipliers and loop oscillators.

A programmable-load CMOS ring oscillator/inverter chain for propagation-delay measurements [PDF]

open access: yes, 1989
A description is given of a test structure consisting of a combination of a ring oscillator and an inverter chain. The circuit can be used to carry out propagation delay measurements on two circuit types and under a number of load conditions.

Structural Control of Metamaterial Oscillator Strength and Electric Field Enhancement at Terahertz Frequencies

open access: yes, 2014
The design of artificial nonlinear materials requires control over the internal resonant charge densities and local electric field distributions. We present a MM design with a structurally controllable oscillator strength and local electric field ...

Heterodyne non-demolition measurements on cold atomic samples: towards the preparation of non-classical states for atom interferometry [PDF]

open access: yes, 2011
We report on a novel experiment to generate non-classical atomic states via quantum non-demolition (QND) measurements on cold atomic samples prepared in a high finesse ring cavity.

Jitter decomposition in ring oscillators [PDF]

open access: yesAsia and South Pacific Conference on Design Automation, 2006., 2006
It is important to separate random jitter from deterministic jitter to quantify their contributions to the total jitter. This paper identifies the limitations of the existing methodologies for jitter decomposition, and develops a new and efficient approach using time lag correlation functions to decompose different jitter components.

Atoms-to-Circuits Simulation Investigation of CNT Interconnects for Next Generation CMOS Technology [PDF]

open access: yes, 2017
In this study, we suggest a hierarchical model to investigate the electrical performance of carbon nanotube (CNT)- based interconnects. From the density functional theory, we have obtained important physical parameters, which are used in TCAD ...

Coherent oscillation by self‐induced gratings in the photorefractive crystal BaTiO_3 [PDF]

open access: yes, 1982
We report here the demonstration of several new optical oscillator configurations including a unidirectional ring oscillator and a self‐pumped phase conjugate mirror. The gain medium is BaTiO_3, pumped by a 632.8‐nm He‐Ne laser at power levels down to 50
