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 …

Microwave signal filtering is a fundamental and central functionality in radio-frequency (RF)
systems. Underpinned by advanced integrated photonics technologies, emerging integrated …

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 light cannot be stopped or directly stored in any media, optical delay lines are usually
used to temporally trap the optical signals. We report a wide-range continuously tunable …

The potential vulnerability to wireless spoofing attacks is still a critical concern for Next
Generation Internet of Things (NGIoT) networks which may result in catastrophic …
