Sub-femtosecond absolute timing precision with a 10 GHz hybrid photonic-microwave oscillator
Sub-femtosecond absolute timing precision optics
2012/5/29
We present an optical-electronic approach to generating microwave signals with high spectral purity. By circumventing shot noise and operating near fundamental thermal limits, we demonstrate 10 GHz si...
Opto-Acoustic Oscillator Using Silicon Mems Optical Modulator
Opto-Acoustic Oscillator MEMS based Optical Modulator RF MEMS resonator Optomechanics
2011/8/5
Abstract: We show operation of a silicon MEMS based narrow-band optical modulator with large modulation depth by improving the electro-mechanical transducer. We demonstrate an application of the narro...
Low phase noise diode laser oscillator for 1S-2S spectroscopy in atomic hydrogen
Low phase noise diode laser oscillator 1S-2S spectroscopy atomic hydrogen
2011/8/16
Abstract: We report on a low-noise diode laser oscillator at 972 nm actively stabilized to an ultra-stable vibrationally- and thermally compensated reference cavity. To increase the fraction of laser ...
The Dirac-Moshinsky oscillator coupled to an external field and its connection to quantum optics
Dirac-Moshinsky oscillator coupled external field connection to quantum optics
2010/11/8
The Dirac-Moshinsky oscillator is an elegant example of an exactly solvable quantum relativistic model that under certain circumstances can be mapped onto the Jaynes-Cummings model in quantum optics. ...
Qubit-oscillator system under ultrastrong coupling and extreme driving
Qubit-oscillator system ultrastrong coupling extreme driving
2010/10/19
We introduce a novel approach to study a driven qubit-oscillator system in the ultrastrong coupling regime, where the ratio g/ between coupling strength and oscillator frequency approaches unity or go...
Transient energy excitation in shortcuts to adiabaticity for the time dependent harmonic oscillator
Transient energy shortcuts adiabaticity time dependent harmonic oscillator
2010/10/21
There is recently a surge of interest to cut down the time it takes to change the state of a quantum system adiabatically. We study for the time-dependent harmonic oscillator the transient energy exci...
