“…The highest upconversion efficiencies has been obtained with QPM devices [81], [82]. These devices are suitable for single-photon counting [81], [83]- [86], spectroscopy [87]- [89], and imaging [45], [90]- [95]. The transverse dimension of standard QPM crystals is typically limited to approximately 1 mm for periodically poled lithium niobate (PPLN) [73], [87].…”

“…For broadband or hyperspectral imaging, a wider range of λIR needs to be upconverted simultaneously, which can be achieved by considering, e.g. non-collinear interaction [87], temperature tuning [45], [88], rotating the crystal [104], tuning the pump wavelength [93], and/or using a broadband pump source [95].

This article provides an extensive survey of nonlinear parametric upconversion infrared (IR) imaging, starting from its origin to date. Upconversion imaging is a successful innovative technique for IR imaging in terms of sensitivity, speed, and noise performance. In this approach, the IR image is frequency upconverted to form a visible/near-IR image through parametric three-wave mixing followed by detection using a silicon-based detector or camera. In 1968 (50 years back), J. E. Midwinter first demonstrated upconversion imaging from shortwave-IR (1.6 μm) to visible (484 nm) wavelength using a bulk lithium niobate crystal. This technique quickly gained interest, and several other groups demonstrated upconversion imaging further into the mid-and far-IR with significantly improved quantum efficiency. Although a few excellent reviews on upconversion imaging were published in the early 1970's, the rapid progress in recent years merits an updated comprehensive review. The topic includes linear imaging, nonlinear optics, and laser science, and has shown diverse applications. The scope of this article is to provide an in-depth knowledge of upconversion imaging theory. An overview of different phase matching conditions for the parametric process and the sensitivity of the upconversion detection system are discussed. Furthermore, different design considerations and optimization schemes are outlined for application-specific upconversion imaging. The article comprises a historical perspective of the technique, its most recent technological advances, specific outstanding issues, and some cutting-edge applications of upconversion in IR imaging.

“…Besides, we discover the phenomenon that the FOV of up-conversion imaging varies when the temperature of PPKTP crystal is changing. The traditional methods of increase FOV is realized by using a broad bandwidth pump laser or illumination laser, a dual illumination wavelength, an ASE illumination source, crystal rotation and designing a temperature gradient inside the crystal [13][14][15][16][17]. All of them aim at satisfying the phase matching condition for different incoming signal angles.…”

Spiral phase contrast is an important and convenient imaging processing technology in edge detection, and a broader field-of-view (FOV) of imaging is a long-pursuing aim to see more regions of the illumination objects. Compared with near-infrared (NIR) spectrum, the up-conversion imaging in visible spectrum benefits from the advantages of higher efficiency detection and lower potential speckle. FOV enhanced and spiral phase contrast up-conversion imaging processing methods by using second order nonlinear frequency up-conversion from NIR spectrum to visible spectrum in two different configurations are presented in this work. By changing the temperature of crystal, controllable spatial patterns of imaging with more than 4.5 times enhancement of FOV is realized in both configurations. Additionally, we present numerical simulations of the phenomenon, which agree well with the experimental observations. Our results provide a very promising way in imaging processing, which may be widely used in biomedicine, remote sensing and up-conversion monitoring.

“…Nonlinear optics (NLO) underpins optical parametric oscillation [1,2], parametric downconversion [3,4], harmonic generation [5,6], sum-frequency generation [7,8], four wave mixing [9,10], etc., with wide applications in optical communications [11,12], biomedical engineering [13], metrology [14], and quantum information [15]. For optical signal processing and detection, NLO techniques can offer significant advantages over their linearoptics counterparts [5,16,17], as demonstrated repeatedly in temporal mode-selective frequency conversion [18][19][20][21][22][23][24], lossless photon shaping [25], spiral phase contrast imaging of the edges [26], and field-of-view enhancement [8,27]. To capitalize on the rich spatial features of light, frequency upconversion has been utilized for mode-selective detection of spatially orthogonal signals in few-mode waveguides [7,28], and more recently in nonlinear crystals to selectively convert overlapping Laguerre-Gaussian (LG) and Hermite-Gaussian (HG) modes [29,30].…”

We experimentally study a nonlinear optical approach to selective manipulation and detection of structured images mixed with turbulent noise. Unlike any existing adaptive-optics method by applying compensating modulation directly on the images, here we account for the turbulence indirectly, by modulating only the pump driving the nonlinear process but not the images themselves. This indirect approach eliminates any signal modulation loss or noise, while allowing more flexible and capable operations. Using specifically sum frequency generation in a lithium niobate crystal, we demonstrate selective upconversion of Laguerre-Gaussian spatial modes mixed with turbulent noise. The extinction reaches ∼40 dB without turbulence, and maintains ∼20 dB in the presence of strong turbulence. This technique could find utilities in classical and quantum communications, compressive imaging, pattern recognition, and so on.
