Compact and low-loss waveguide devices are highly desired in the development of THz-wave circuits. Nonradiative dielectric (NRD) waveguides having simple structures and very low loss are promising platforms for THz-wave circuits, and previously some

By improving both effective-index (EI) matching and leakage-factor (LF) matching at multiple wavelengths, a method to achieve a wideband-efficient uniform subwavelength grating coupler (SWGC) has been theoretically demonstrated. First, the root-mean-

One of the remarkable choices for active smart window technology is adopting a metal active layer via reversible metal electrodeposition (RME). As the metal layer efficiently blocks the solar energy gain, even a hundred-nanometer-thick scale, RME-bas

Photonic integrated circuits (PIC) find applications in the fields of microwaves, telecoms and sensing. Generally, PICs are fabricated on a base of isotropic materials such as SOI, Si3N4, etc. However, for some applications, anisotropic substrates su

We report on subwavelength reflective gratings for hyperspectral applications operating in a very large spectral band (340–1040 nm). Our study concerns a blazed-binary grating having a period of 30 μm and composed of 2D subwavelength structures wi

Most of the conventional photonic crystal (PhC) slab waveguides have a photonic bandgap (PBG) only for one polarization state of two orthogonal polarization states. In this paper, westudy on an absolute PBG that can realize PBG for both polarizations
