Characterization of RGB LEDs as Emitter and Photodetector for LED-to-LED Communication [PDF]
2020 12th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP), 2020 Visible Light Communication (VLC) has rapidly grown over the last decade. However, unlike RF technologies, VLC has a simplex channel since two different devices are used for transmitting and receiving. This increases the cost and complexity of the transceiver circuit when a bidirectional link is required.

Remote plasmonic-enhanced Raman spectroscopy with the plasmon-molecule coupling in distance over 100 nm [PDF]
EPJ Web of Conferences, 2023 We propose remote plasmonic-enhanced Raman scattering (RPERS) spectroscopy for molecular sensing and imaging applications. RPERS requires no contact between analyte molecules and metallic nanostructures, which overcomes the limitations of surface ...

Experimental Characterization of RGB LED Transceiver in Low-Complexity LED-to-LED Link [PDF]
Sensors, 2020 This paper proposes a low-complexity and energy-efficient light emitting diode (LED)-to-LED communication system for Internet of Things (IoT) devices with data rates up to 200 kbps over an error-free transmission distance up to 7 cm. The system is based on off-the-shelf red-green-blue (RGB) LEDs, of which the red sub-LED is employed as photodetector in
