“…For the APE waveguides, the conversion efficiency to the TM 01 optical mode at 780 nm was higher than the conversion efficiency to the fundamental mode. These results were consistent with Galvanauskus et al [31], who hypothesized that inefficient conversion between the fundamental pump mode and the signal/idler mode may occur because there is a dead layer~0.5 microns below the surface of the protonexchanged region in which the nonlinear optical coefficient is reduced [33]. For the Ti-indiffused waveguides, the conversion to the fundamental mode at 780 nm was more efficient than conversion to the TM 01 mode.…”

“…One can also see that the TM 00 780 nm mode is concentrated closer to the surface of the lithium niobate crystal, and therefore, this optical mode is more sensitive to surface-dependent effects. Galvanauskas et al [31] performed a similar analysis for proton-exchanged waveguides, and the mode field distribution as a function of depth was comparable to the distribution that we calculated for the Ti-indiffused waveguides. Therefore, our research focused on a detailed study of photon pair creation from the TM 00 and the TM 01 780 nm mode for both APE and Ti-indiffused waveguides.…”

To support quantum technologies that require entangled photon pairs and/or heralded photons for operation, a photon pair source was developed that uses periodically poled lithium niobate (PPLN) waveguides that are coupled to optical fibers. Both Ti-indiffused and annealed proton-exchanged (APE) waveguide technologies were studied, and waveguide/fiber interfaces were designed to increase the coupling efficiency of the photon pairs into optical fiber. PPLN waveguide devices were fabricated and the optical loss, wavelength conversion efficiency, and heralding efficiency were measured. The maximum heralding efficiencies achieved were 75 and 68% for Ti-indiffused and APE waveguides, respectively. A compact photon pair source based on a packaged PPLN waveguide device and commercially available fiber optic components is presented

“…Second-order nonlinear processes, like sum-and difference-frequency generation, spontaneous down-conversion and optical parametric amplification [1], are essential for a number of applications, ranging from spectroscopy, free-space communication, biochemical sensing, medical therapy [2], ultra-fast optical signal processing [3], lowest-noise optical amplification [4], and quantum physics [5]. Since at least one of the frequencies involved in a three-wave mixing process is necessarily well separated from the others, second-order processes represent additionally an excellent candidate for generating mid-IR and far-IR wavelengths [6].…”

Abstract:We describe a concept for second-order nonlinear optical processes in silicon photonics. A silicon-organic hybrid (SOH) double slot waveguide is dispersion-engineered for mode phase-matching (MPM). The proposed waveguide enables highly efficient nonlinear processes in the mid-IR range. With a cladding nonlinearity of χ (2) = 230 pm/V and 20 dBm pump power at a CW wavelength of 1550 nm, we predict a gain of 14.7 dB/cm for a 3100 nm signal. The suggested structure enables for the first time efficient second-order nonlinear optical mixing in silicon photonics with standard technology. ©2012 Optical Society of America

“…Many methods have been reported to obtain variable wavelength conversion and broaden the bandwidth by chirping the optical superlattice period. Linearly chirped gratings [21] , segmented gratings [22] , phase-shifted gratings [23] and multiple-wavelength phase-matching gratings [15]- [17][24] [25] were theoretically proposed and/or experimentally realized.…”

In this paper, we proposed a variable operation of a DC-OFS based on double SFG+DFG (Double-SFG+DFG-OFS) nonlinearity process for the first time. We studied the principle and configuration of three DC-OFS in detail both theoretically and experimentally. In order to compare with Double-DFG-OFS and Double-SHG+DFG-OFS, we also used two four-channel-controlling multiple-quasi-phase-matched LiNbO3 wavelength converters and got ten different outputs spreading across a wavelength range of as broad as 35 nm by changing the combination of two controlling wavelengths of the two wavelength converters. And one channel signal was converted to shorter and longer wavelength and the same wavelength by changing the controlling wavelengths. We got higher conversion efficiency compared with the other two DC-OFSs mentioned above. We used novel M-QPM-LN wavelength converters having a continuouslyphase-modulated domain structure, which can be operated by multiple pump wavelengths with minimum loss of efficiency. The periods were 14.8µm. The phase of the periodic poling was continuously modulated to satisfy the QPM condition at four different wavelengths. The frequency spacing of control signal-b is twice as large as the control signala. The operating temperatures were 102.5 and 100.5 C for the first and the second QPM-LN wavelength converters, respectively.
