1D quasi-bound states in the continuum with large operation bandwidth in the ω～k space for nonlinear optical applications
文献摘要：
The phenomenon of bound state in the continuum(BIC)with an infinite quality factor and lifetime has emerged in recent years in photonics as a new tool to manipulate light-matter interactions.However,most of the investigated structures only support BIC resonances at very few discrete points in the ω～k space.Even when the BIC is switched to a quasi-BIC(QBIC)resonance through perturbation,its frequency will still be located within a narrow spectral band close to that of the original BIC,restricting their applications in many fields where random or multiple input frequencies beyond the narrow band are required.In this work,we dem-onstrate that a new set of QBIC resonances can be supported by using a special binary grating consisting of two alternatingly aligned ridge arrays with the same period and zero-approaching ridge width difference on a slab waveguide.These QBIC resonances are distributed continuously over a broad band along a line in the ω～k space and can thus be considered as ID QBICs.With the Q factors generally affected by the ridge difference,it is now possible to arbitrarily choose any frequencies on the dispersion line to achieve significantly enhanced light-matter interactions,facilitating many applications where multiple input wavelengths are required;e.g.,sum or difference frequency generations in nonlinear optics.
