Abstract Hotspots are high-intensity electromagnetic zones that form, for example, at the interstitials of plasmonic nanoaggregates, resulting in a considerable rise in the enhancement factor. However, it is inevitable to achieve specific nanometric

Proposal for metal–insulator–metal plasmonic power splitter and demultiplexer suitable for implementation in optical switches

Autor: Mohammad Reza Ghasemi, Mohammad Sajjad Bayati

Publikováno v: IET Optoelectronics, Vol 15, Iss 4, Pp 200-206 (2021)

Abstract The authors propose a nanoplasmonic structure based on metal–insulator–metal (MIM) waveguides which consists of a 3 db power splitter and a side‐coupled nanocavity placed between its two output ports. The proposed structure is analysed

Semiconductor racetrack resonator coupled to an S‐bent waveguide: Influence of the coupling coefficients on the unidirectional operation

Autor: Giuseppe Giannuzzi, Paolo Bardella

Publikováno v: IET Optoelectronics, Vol 15, Iss 3, Pp 131-138 (2021)

Abstract Semiconductor ring lasers have attracted remarkable interest as laser sources in photonic integrated circuits. They result in bidirectional laser owing to the rotation symmetry between the two counter‐propagating modes of the ring cavity.
