“…Nonlinear photonic crystals (NPCs) with a homogeneous change of the linear refraction index and a two-dimensional (2D) periodic variation of the nonlinear quadratic susceptibility have been suggested by Berger [1998Berger [ , 1999 as a 2D analog of the QPM structures. Both theoretical and experimental results published so far show that this kind of structures can effectively be employed as a host media for realizing many different types of multistep-cascading parametric processes (see, e.g., Broderick, Ross, Offerhaus, Richardson, and Hanna [2000]; Saltiel and Kivshar [2000a]; de Sterke, ; Chowdhury, Hagness, and McCaughan [2000]).…”

We present a comprehensive overview of different types of parametric interactions in nonlinear optics which are associated with simultaneous phase-matching of several optical processes in quadratic nonlinear media, the so-called multistep parametric interactions. We discuss a number of possibilities of double and multiple phase-matching in engineered structures with the sign-varying second-order nonlinear susceptibility, including (i) uniform and non-uniform quasi-phase-matched (QPM) periodic optical superlattices, (ii) phase-reversed and periodically chirped QPM structures, and (iii) uniform QPM structures in non-collinear geometry, including recently fabricated two-dimensional nonlinear quadratic photonic crystals. We also summarize the most important experimental results on the multi-frequency generation due to multistep parametric processes, and overview the physics and basic properties of multi-color optical parametric solitons generated by these parametric interactions.

“…Two-dimensional x photonic crystal structure. The shapes of the x regions are chosen in such a way as to force the nonlinear emission of the structure under illumination to assume a certain requested shape (nonlinear holography) A further refinement of the notion of a nonlinear photonic crystal has led to the proposal of nonlinear materials which, rather than being periodically structured in two dimensions, would be structured in such a way as to adapt the harmonic wave to the spatial distribution of the fundamental excitation wave (Berger 1999). This leads to the possibility of developing a genuine nonlinear holography, according to a principle schematically represented here in Fig.…”

“…Alternatively a HeXLN crystal could be used as an efficient monolithic optical parametric oscillator [2]. Last, we note that NPCs are a specific example of more general nonlinear holograms which would convert a beam profile at one wavelength to an arbitrary profile at a second wavelength [10]. This would be a generalization of the concepts of Imeshev et al who converted a Gaussian profile beam at the fundamental to a square top second harmonic using transversely patterned periodically poled lithium niobate [11].…”

We report on the fabrication of what we believe is the first example of a two-dimensional (2D) nonlinear photonic crystal [Berger, Phys. Rev. Lett. 81, 4136 (1998)], where the refractive index is constant but where the 2nd order nonlinear susceptibility is spatially periodic. Such crystals allow for efficient quasi-phase-matched 2nd harmonic generation using multiple reciprocal lattice vectors. External 2nd harmonic conversion efficiencies >60% were measured with picosecond pulses. The fabrication technique is extremely versatile and should allow for the fabrication of a broad range of 2D crystals including quasicrystals.
