Abstract:We propose and demonstrate phase-sensitive amplification based on cascaded second harmonic generation and difference frequency generation within a periodically poled lithium niobate waveguide. Excellent agreement between our numerical simulations and proof-of-principle experiments using a 3-cm waveguide device operating at wavelengths around 1550 nm is obtained. Our experiments confirm the validity and practicality of the approach and illustrate the broad gain bandwidths achievable. Additional simulation results show that the maximum gain/attenuation factor increases quadratically with input pump power, reaching a value of ±19.0dB at input pump powers of 33 dBm for a 3 cmlong waveguide. Increased gains/reduced powers for a fixed gain could be achieved using longer crystals.

“…This process may therefore be utilized in distributed multi-wavelength imaging or image processing, where objects are placed in the path of one or more of these fields of different wavelengths and the intensities or cross-correlations are measured. Two examples of phenomena based on three-wave mixing, optical parametric oscillation (OPO) and optical parametric amplification (OPA), have been studied extensively and many interesting phenomena of spatial correlation [11], pattern formation [12,13], and reduced-noise image amplification [14,15] have been reported.…”

Entangled photons, generated by spontaneous parametric down-conversion from a second-order nonlinear crystal, present a rich potential for imaging and image-processing applications. Since this source is an example of a threewave mixing process, there is more flexibility in the choices of illumination and detection wavelengths and in the placement of object(s) to be imaged.Moreover, this source is entangled, a fact that allows for imaging configurations and capabilities that cannot be achieved using classical sources of light.In this paper we examine a number of imaging and image-processing configurations that can be realized using this source. The formalism that we utilize facilitates the determination of the dependence of imaging resolution on the physical parameters of the optical arrangement.

“…In recent years, there has been an increasing interest in the field of quantum imaging, in which nonclassical states of light are used as light sources [1,2,3,4,5,6,7,8,9,10,11,12]. Special attentions are focused on entangled-photon coincidence imaging [1,2,3,4,5,6,7,8].…”

Incoherent Coincidence Imaging and Its Applicability in X-ray Diffraction

Entangled-photon coincidence imaging is a method to nonlocally image an object by transmitting a pair of entangled photons through the object and a reference optical system respectively. The image of the object can be extracted from the coincidence rate of these two photons. From a classical perspective, the image is proportional to the fourth-order correlation function of the wave field. Using classical statistical optics, we study a particular aspect of coincidence imaging with incoherent sources. As an application, we give a proposal to realize lensless Fourier-transform imaging, and discuss its applicability in X-ray diffraction.
