Second harmonic generation slot waveguide

By Admin

We theoretically propose an internal asymmetric plasmonic slot waveguide (IAPSW), containing two different materials in the slot region. The IAPSW is used for second harmonic generation (SHG) at a wavelength of 1.55 μm. The required phase matching condition is satisfied between the 0th-order mode at the fundamental frequency and the 1st-order mode at the second harmonic frequency.

Loop-mirror-based slot waveguide refractive index sensor Loop mirror has been widely used in fiber optical devices and systems for it provides a smart way to make use of the fiber birefringence properties and can enhance the sensitivity greatly. On the other hand, slot waveguide is very promising for optical sensing applications because of their peculiar spatial mode profile. In this paper, we propose and analyze a loop-mirror-based slot waveguide Second Harmonic Generation from a Nanopatterned Isotropic Second harmonic generation (SHG) from a nanopatterned isotropic nonlinear material (GaAs) located inside the subwavelength gaps of a metallic coaxial array is demonstrated. The SHG results from the strong electromagnetic fields in the vicinity of the coaxial gaps; the signal strength is comparable to that from z-cut LiNbO3 even though the path length is much shorter (∼100 nm compared to 14 μm).

Jan 04, 2008 · We theoretically analyse quasi-phase matched second harmonic generation in a quadratic slot waveguide. Our results show that in this system both fundamental frequency and second harmonic (SH) modes can be confined in a nano-sized low-index region with the mode overlap integral intensity two orders larger than that achieved in the form birefringence phase matching slot waveguide and the
