Plasmonic wavelength-dependent optical switch
Optics Express, 2023 We design and experimentally demonstrate an optical switch based on the interference of plasmonic modes in whispering gallery mode (WGM) antennas. Simultaneous excitation of even and odd WGM modes, enabled by a small symmetry breaking via non-normal illumination, allows switching the plasmonic near field between opposite sides of the antenna, depending

Performance analysis of a 2-D time-wavelength OCDMA wavelength-aware receiver with beat noise [PDF]
, 2006 The effect of beat noise on two-dimensional time-wavelength optical code-division multiple-access systems utilising wavelength-aware receivers is examined. A derivation of a general formula for the bit error probability taking into consideration multiple

Wavelength-Dependent Photoreactivity of Root Exudates from Aquatic Plants under UV-LED Irradiation
, 2022 Aquatic plants and their root exudates play important roles in the removal of trace organic contaminants in aquatic environments. However, the wavelength-dependent photogeneration of reactive species (RS) and photodegradation of organic contaminants by ...

Wavelength-dependent holographic impedance metasurfaces
Optics Express, 2021 Impedance metasurface can establish a link between an electromagnetic surface wave and spatial wave and hence has attracted much attention of researchers in recent years. The holographic method, which is well known in the optical area, has also the great ability to shape the radiated beams in the microwave band by introducing the concept of surface ...

Wavelength-Dependent Bifunctional Plasmonic Photocatalysis in Au/Chalcopyrite Hybrid Nanostructures
, 2022 Excited, or “hot” charge carrier generation and transfer driven by the decay of localized surface plasmon resonances (LSPRs) are key steps in plasmonic photocatalysis. Hybrid structures that contain both metal and semiconductor building blocks facilitate

Predicting wavelength-dependent photochemical reactivity and selectivity
Nature Communications, 2021 Predicting the conversion and selectivity of a photochemical reactions is challenging. Here, the authors introduce a framework for the quantitative prediction of the time-dependent progress of a photoligation reaction and predict LED-light induced ...

Efficient all-optical wavelength converter using saw-tooth pulses [PDF]
, 2009 Wavelength conversion is a key WDM function which is used to avoid wavelength blocking, thus allowing greater flexibility in the network design. Wavelength conversion of an intensity modulated signal can be simply achieved by employing cross-phase ...
