Multiplexing in photonics as a resource for optical ternary content-addressable memory functionality. [PDF]

Nanophotonics, 2023
Abstract In this paper, we combine a Content‐Addressable Memory (CAM) encoding scheme previously proposed for analog electronic CAMs (E‐CAMs) with optical multiplexing techniques to create two new photonic CAM architectures—wavelength‐division multiplexing (WDM) optical ternary CAM (O‐TCAM) and time‐division multiplexing (TDM) O‐TCAM. As an example, we

Broadband high-efficiency near-infrared graphene phase modulators enabled by metal-nanoribbon integrated hybrid plasmonic waveguides. [PDF]

Nanophotonics, 2022
Abstract The phase modulator is a key component in optical communications for its phase modulation functions. In this paper, we numerically demonstrate a variety of ultra‐compact high‐efficiency graphene phase modulators (GPMs) based on metal–nanoribbon integrated hybrid plasmonic waveguides in the near‐infrared region.

Low‐loss and broadband InP mirror‐based out‐of‐plane optical coupler

Electronics Letters, Volume 59, Issue 5, March 2023., 2023
We developed a mirror‐based out‐of‐plane optical coupler (MOOC) for InP photonic integrated circuits. The coupler has the coupling loss and alignment tolerance comparable to those of a conventional edge coupler. A small wavelength‐dependent loss was observed over the 100‐nm wavelength bandwidth at chip temperatures of 25, 45, and 65°C.

Fully On‐Chip Microwave Photonic Instantaneous Frequency Measurement System

Laser &Photonics Reviews, Volume 16, Issue 11, November 2022., 2022
A fully on‐chip microwave photonic instantaneous frequency measurement (MWP IFM) system is demonstrated, based on hybrid integration of InP, Si photonics, and CMOS electronics platforms. The unprecedented integration level brings great promotion to the IFM performances, including a broad measurement range of 2–34 GHz, ultralow error of 10.85 MHz, and a
