As a fundamental optical approach to interferometry, Sagnac interference has been widely
used for reflection manipulation, precision measurements, and spectral engineering in …

In the late nineteenth century, Heinrich Hertz demonstrated that the electromagnetic
properties of materials are intimately related to their structure at the subwavelength scale by …

Segmenting silicon waveguides at the subwavelength scale produce an equivalent
homogenous material. The geometry of the waveguide segments provides precise control …

On-chip mode-manipulation is one of the most important physical fundamentals for many
photonic integrated devices and circuits. In the past years, great progresses have been …

As the demand for display technology in consumer electronics and lighting panels
increases, thin, light, high‐quality, and more cost‐effective light‐emitting devices are …

It is a remarkable and straightforward approach to customize the dispersion and nonlinear
properties of the photonic devices without varying the composition of the material by …

Coupling among closely packed waveguides is a common optical phenomenon, and plays
an important role in optical routing and integration. Unfortunately, this coupling property is …

Abstract Broadband Silicon-On-Insulator (SOI) directional couplers are designed based on a
combination of curved and straight coupled waveguide sections. A design methodology …

Dynamically encircling the exceptional point (EP) of an anti‐parity‐time (anti‐PT) symmetric
system can achieve chiral mode switching between symmetry‐broken eigenmodes, which is …

We demonstrate a novel polarization beam splitter (PBS) based on a subwavelength grating
(SWG) multimode interference (MMI) coupler for the silicon-on-insulator platform. The …
