“…For centro-symmetric constituent materials, phase-matched direct third-harmonic generation (THG) has been reported for 3D polymer-based opal structures [368] and for 1D liquid-crystal structures [369]. Furthermore, phasematched nondegenerate four-wave maxing has been reported for 1D chalcogenide-based photonic crystals [370].…”

Periodic nanostructures in photonics facilitate a far-reaching control of light propagation and light-matter interaction. This article reviews the current status of this subject, including both recent progress and well-established results. The primary focus is on the basic physical principles and potential applications associated with the existence of Bragg scattering, photonic band structures, and engineered effective-medium properties in periodic dielectric and metallo-dielectric systems. In addition, we discuss advantages and limitations of various theoretical and numerical approaches as well as of those fabrication techniques that have specifically been developed for this field.

“…3 For example, a QPM structure with a linearly varying wave vector along the direction of wave propagation can be used to achieve effective nonlinear pulse compression 18,19 and to implement various frequency-conversion processes. [20][21][22][23] In this work, we achieve a considerable advancement in this technology through the design and fabrication of chirped periodically poled lithium niobate (CPPLN) nonlinear crystals whose modulation period of nonlinear susceptibility varies along the propagation direction. We demonstrate both theoretically and experimentally that CPPLN can support multiple orders of QPM with finite bandwidth and therefore, allows for simultaneous broadband SHG and THG with high conversion efficiency from a single crystal.…”

Ultrabroadband laser sources are highly desirable in a wide variety of modern science disciplines ranging from physics, chemistry and materials science to information communications and processing. Here we present the design and fabrication of a chirped periodically poled lithium niobate (CPPLN) nonlinear photonic crystal that supports multiple orders of quasiphase matching with finite bandwidth and allows for the simultaneous broadband generation of second and third harmonics with high conversion efficiency. Moreover, the chirp rate has a significant influence on the conversion efficiency and bandwidth. The CPPLN scheme offers a promising approach for the construction of short-wavelength laser sources and enables the generation of the three primary colors-red, green and blue-from a single crystal, which may have potential applications in large-screen laser displays. Keywords: chirped periodically poled lithium niobate; quasiphase matching; second-harmonic generation; third-harmonic generation INTRODUCTION Ultrabroadband laser sources are highly desirable in a wide variety of modern science disciplines ranging from physics, chemistry and materials science to information communications and processing. Laser gain media that are capable of short-pulse generation are available but limited, and they cover only a small portion of the optical spectrum. Shortly after the creation of the first laser in 1960, the door to nonlinear optics was opened because of the discovery of second-harmonic generation (SHG).1 Broad-bandwidth and high-conversion-efficiency SHG, third-harmonic generation (THG), higher-order-harmonic generation and various frequency-mixing and parametric-conversion processes have all provided fascinating routes toward the considerable expansion of the spectral range of laser sources.To realize high-efficiency SHG, THG and other optical parametric processes, nonlinear optical materials are required to simultaneously satisfy the phase-matching condition and possess large nonlinear optical coefficients in the phase-matching direction. Although many natural nonlinear crystals have large nonlinear coefficients in certain directions, proper phase matching cannot always be achieved because of the dispersion of the material. Thus, the optical birefringent properties of certain birefringent nonlinear crystals are often utilized to compensate for the material dispersion and achieve phase matching. However, the stringent conditions for birefringent phase matching greatly limit the extension of the optical frequency. As an alternative approach, quasiphase matching (QPM), which was first proposed in 1962, 2 launched a new era in nonlinear optics because of several advantages it offers over conventional birefringence phase matching in the frequency-conversion process. These advantages include phase matching in materials that have high nonlinear optical coefficients but

“…(χ (3) third-harmonic generation in a bulk periodic structure, with no cavity, was considered in Ref. 43.) In a χ (3) medium, there are also self/cross-phase modulation phenomena (nonlinear frequency shifts) that, unchecked, will prevent 100% conversion by making the frequency ratio = 3.…”

We derive general conditions for 100% frequency conversion in any doubly resonant nonlinear cavity, for both second-and third-harmonic generation via χ (2) and χ (3) nonlinearities. We find that conversion efficiency is optimized for a certain "critical" power depending on the cavity parameters, and assuming reasonable parameters we predict 100% conversion using milliwatts of power or less. These results follow from a semi-analytical coupled-mode theory framework which is generalized from previous work to include both χ (2) and χ (3) media as well as inhomogeneous (fully vectorial) cavities, analyzed in the high-efficiency limit where down-conversion processes lead to a maximum efficiency at the critical power, and which is verified by direct finite-difference time-domain (FDTD) simulations of the nonlinear Maxwell equations. Explicit formulas for the nonlinear coupling coefficients are derived in terms of the linear cavity eigenmodes, which can be used to design and evaluate cavities in arbitrary geometries.
