High-efficiency second-harmonic generation in doubly-resonant χ(²) microring resonators.
By directly simulating Maxwell's equations via the finite-difference time-domain (FDTD) method, we numerically demonstrate the possibility of achieving high-efficiency second harmonic generation (SHG) in a structure consisting of a microscale doubly-resonant ring resonator side-coupled to two adjacent waveguides. We find that ≳ 94% conversion efficiency can be attained at telecom wavelengths, f...
متن کاملConsiderably Enhanced Second-Harmonic Generation in Resonant U-Shaped Nano-Structures
In this paper, we perform a detailed study of the spectral response of the gold U-shaped nano-structures for different geometrical parameters and polarizations in order to obtain significant localization factor in the wavelength 1.55 μm. The obtained near-field distribution of electric fields reveals that resonances in these nano-structures correspond to the even and odd plasmonic modes dependi...
متن کاملNonlinear harmonic generation and devices in doubly resonant Kerr cavities
We describe a theoretical analysis of the nonlinear dynamics of third-harmonic generation →3 via Kerr 3 nonlinearities in a resonant cavity with resonances at both and 3 . Such a doubly resonant cavity greatly reduces the required power for efficient harmonic generation, by a factor of V /Q2, where V is the modal volume and Q is the lifetime, and can even exhibit 100% harmonic conversion effici...
متن کاملModification of pattern formation in doubly resonant second-harmonic generation by competing parametric oscillation.
We analyze pattern formation in doubly resonant intracavity second-harmonic generation in the presence of competing nondegenerate parametric downconversion. We show that for positive cavity detuning of the fundamental frequency the threshold for parametric oscillation is lower than that of transverse, pattern forming instabilities. The parametric oscillation strongly modifies the pattern dynami...
متن کاملSecond-harmonic generation in doubly resonant microcavities with periodic dielectric mirrors.
Strong enhancement of second-harmonic generation (SHG) is expected in one-dimensional microcavities when double resonance for the pump and the harmonic fields, as well as phase matching, are achieved. The realization of a doubly resonant microcavity with dielectric mirrors made of nonbirefringent materials is difficult because of the refractive index dispersion of the constituent media. Here we...
