In this paper, we investigate the mode sensitivity (S mode) of subwavelength grating slot
(SWGS) waveguides. S mode is an important parameter in various waveguide-based …

Structural slow light is the dispersion engineering process by which the group velocity of
light can be drastically reduced in a periodic waveguide structure. Enabling large group …

High-performance optical beam splitters are of fundamental importance for the development
of advanced silicon photonics integrated circuits. However, due to the high refractive index …

Subwavelength grating metamaterial racetrack ring resonator (SGMRTR) increases the
coupling strength between the bus waveguide and the ring resonator and thus better …

Slow light is a very important concept in nanophotonics, especially in the context of photonic
crystals. In this work, we apply our previous design of band-edge slow light in silicon …

Approaches to provide chip-scale aqueous chemical sensing for environmental and health
monitoring via a photonic integrated circuit (PIC) technology are showing promise. To meet …

Polarization independent silicon-on-insulator nanowires are highly sought after, due the
inherent high birefringence of this material platform. State-of-the-art designs of non …

Sub-wavelength grating (SWG) metamaterials have garnered a great interest for their
singular capability to shape the propagation of light. However, practical SWG …

An ultrabroadband and fabrication-tolerant mode (de) multiplexer (De) MUX is proposed
and optimized by inserting subwavelength gratings (SWGs) into a three-waveguide coupler …

In this Letter, we demonstrate a new, to the best of our knowledge, kind of photonic
waveguide, in which the light propagates in the overlap of sub-wavelength patterned …
