Silicon photonics has attracted tremendous interest from academia and industry, as the
fabrication of the silicon family of photonic devices is mostly compatible with the microelectronics …

In this work, a novel soft-hard template method towards the direct fabrication of graphene
films on silicon/silica substrate is developed via a tri-constituent self-assembly route. Using …

Mode and polarization‐division multiplexing technologies (MDM and PDM) can offer considerable
parallelism for optical multiplexing biosensors, complex optical neural networks, and …

We analyze transmission characteristics of two coupled identical cavities, of either standing-wave
(SW) or traveling-wave (TW) type, based on temporal coupled mode theory. Mode …

Virtual reality (VR) and augmented reality (AR) are revolutionizing our lives. Near-eye displays
are crucial technologies for VR and AR. Despite the rapid advances in near-eye display …

Ever‐growing demands of bandwidth, computing speed, and power consumption are now
accelerating the transformation of computing research, as work‐at‐home becomes a new …

We demonstrate a compact silicon polarization beam splitter (PBS) based on grating-assisted
contradirectional couplers (GACCs). Over 30-dB extinction ratios and less than 1-dB …

We review the current status of mode-division multiplexing (MDM) techniques in fibers and on
chips. Three system applications are introduced, including quasi-single mode transmission…

We have experimentally compared the performances of optical millimeter-wave generation
or up-conversion using external modulators based on different modulation schemes. The …

Subwavelength structures such as subwavelength gratings (SWGs) and subwavelength
metamaterials are capable of tailoring the optical properties of materials and controlling the flow …
