Integrated Optics Using High Contrast Gratings

High contrast grating (HCG) is a new class of optical grating with many distinct features that are not found in conventional gratings [1–6]. These features include broadband ultrahigh reflectivity, broadband ultrahigh transmission, or very high quality factor resonance, for optical beam surface-normal or in oblique incidence to the direction of grating periodicity. Furthermore, these features c...

Monolithically integrated multi-wavelength VCSEL arrays using high-contrast gratings.

We propose a novel design for multi-wavelength arrays of vertical cavity surface-emitting lasers (VCSELs) using high-contrast gratings (HCGs) as top mirrors. A range of VCSEL cavity wavelengths in excess of 100 nm is predicted by modifying only the period and duty-cycle of the high-contrast gratings, while leaving the epitaxial layer thickness unchanged. VCSEL arrays fabricated with this novel ...

High-Contrast Gratings based Spoof Surface Plasmons

In this work, we explore the existence of spoof surface plasmons (SSPs) supported by deep-subwavelength high-contrast gratings (HCGs) on a perfect electric conductor plane. The dispersion relation of the HCGs-based SSPs is derived analyt- ically by combining multimode network theory with rigorous mode matching method, which has nearly the same form with and can be degenerated into that of the S...
