1D microcavity–based optical parametric oscillator: generation of balanced twin beams in strong and weak coupling regime
نویسندگان
چکیده
We report on a detailed experimental investigation of interbranch parametric scattering processes in onedimensional semiconductor microcavities. Band dispersion and corresponding far field emission patterns are studied by polarization resolved and power dependence measurements under resonant and non-resonant excitation at normal incidence. We demonstrate the realization of optical parametric oscillation of balanced twin beams which are degenerate in energy and split in momentum space. This achievement is shown for both the strong and the weak coupling regime highlighting the versatility of this peculiar microcavity system.

Optical parametric oscillaton in 1D semiconductor microcavities
We present an experimental investigation of parametric scattering processes and optical parametric oscillations in wire shaped, one-dimensional semiconductor microcavities. Far field emission patterns and corresponding band dispersion are studied by polarization resolved measurements and power dependence measurements under resonant and non-resonant excitation. The multiplicity of the photonic b...
متن کاملTemporal properties of counter-propagating twin beams in a Mirrorless Optical Parametric Oscillator
Twin photon pairs generated through parametric downconversion (PDC) in a χ2 medium is one of the most widely used source of entanglement. We focus here on a nonconventional geometry in which one of the twin photons propagates in the opposite direction with respect to the pump beam exploiting quasi-phase-matching in a periodically poled crystal. Through predicted almost 50 years ago, this new PD...
متن کاملQuantum interference of ultrastable twin optical beams.
We report the first measurement of the quantum phase-difference noise of an ultrastable nondegenerate optical parametric oscillator that emits twin beams classically phase locked at exact frequency degeneracy. The measurement illustrates the property of a lossless balanced beam splitter to convert number-difference squeezing into phase-difference squeezing, and thus provides indirect evidence f...

A type-II phase matched optical parametric oscillator is investigated for the generation of intensity correlated twin photon beams using potassium titanyl phosphate (KTP) as a nonlinear medium. The input pump source is a Kr'-ion laser at XP = 531nm with signal and idler twin photon beams at X,, = 1.06gm. Mirror and crystal losses were characterized for use in cavities of two-and three-piece con...
متن کاملTwin beams, nonlinearity, and walk-off in optical parametric oscillators
We study the quantum properties of the spatially tilted macroscopic signal beams in the transverse pattern formed in a degenerate optical parametric oscillator above threshold. We show that walk-off leads to an imbalance in the intensities and fluctuations of these beams when nonlinear multimode interactions are effective. Still, quantum correlations between the two beams are preserved, so that...
