Quantum theory of light and noise polarization in nonlinear optics.
We present a consistent quantum theory of the electromagnetic field in nonlinearly responding causal media, with special emphasis on Chi(2) media. Starting from QED in linearly responding causal media, we develop a method to construct the cubic Hamiltonian expressed in terms of the complex nonlinear susceptibility in a quantum mechanically consistent way. In particular, we show that the method ...
متن کاملQuantum Optics Theory of Electronic Noise in Coherent Conductors.
We consider the electromagnetic field generated by a coherent conductor in which electron transport is described quantum mechanically. We obtain an input-output relation linking the quantum current in the conductor to the measured electromagnetic field. This allows us to compute the outcome of measurements on the field in terms of the statistical properties of the current. We moreover show how ...
متن کاملExperimental test of the high-frequency quantum shot noise theory in a quantum point contact.
We report on direct measurements of the electronic shot noise of a quantum point contact at frequencies nu in the range 4-8 GHz. The very small energy scale used ensures energy independent transmissions of the few transmitted electronic modes and their accurate knowledge. Both the thermal energy and the quantum point contact drain-source voltage V_{ds} are comparable to the photon energy hnu le...
متن کاملQuantum Noise and Superluminal Propagation
Causal “superluminal” effects have recently been observed and discussed in various contexts. The question arises whether such effects could be observed with extremely weak pulses, and what would prevent the observation of an “optical tachyon.” Aharonov, Reznik, and Stern (ARS) [Phys. Rev. Lett. 81, 2190 (1998)] have argued that quantum noise will preclude the observation of a superluminal group...
متن کاملMulti –Conjugate Adaptive Optics Test-bed for horizontal propagation
Our program for the upgrade of the Naval Prototype Optical Interferometer with large telescopes and adaptive optics has produced a test-bed for the in system evaluation and testing of our MEMs adaptive optics components and system performances. We have already reported in recent publications the basic characteristics of the test-bed. In order to improve the capabilities of such laboratory set-u...
