Real photonic waveguides are affected by structural imperfections due to fabrication
tolerances that cause scattering phenomena when the light propagates through. These …

Fiber to chip coupling is a critical aspect of any integrated photonic circuit. In terms of ease of
fabrication as well as wafer-scale testability, surface grating couplers are by far the most …

Polarization management is of paramount importance in integrated optics, particularly for
highly birefringent photonic platforms such as silicon-on-insulator. In this paper, we present …

We presented a novel design of a microring resonator based on a subwavelength grating
(SWG) double-slot waveguide (WG) due to its enhanced sensitivity. The paper is divided into …

In this paper we demonstrate silicon on insulator (SOI) sub-wavelength grating (SWG)
optical components for integrated optics and sensing. Light propagation in SWG devices is …

We present an air-cladding apodized focusing subwavelength grating that can effectively
couple two polarizations into a single waveguide. For the transverse magnetic mode,− 3.2 …

As most integrated optics platforms, silicon offers only a fixed set of material refractive
indices for designing devices. The ability of sub-wavelength patterned structures to …

Integrated metamaterials are redefining the capabilities of silicon photonic chips. In
providing lithographic control over dielectric permittivity, dispersion and anisotropy, they are …

Subwavelength gratings (SWG) are photonic structures with a period small enough to
suppress diffraction, thereby acting as artificial dielectric materials, also called all-dielectric …

Moore's Law has set great expectations that the performance of information technology will
improve exponentially until at least the end of this decade. Although the physics of silicon …
