Hybrid Plasmonic Nanoantenna With the Capability of Monolithic Integration With Laser and Photodetector on InP Substrate

چکیده مقاله

Abstract—In this paper, a novel InP-based hybrid plasmonic
(HP) bowtie nanoantenna with director was proposed that
can serve as a good alternative to the silicon-on-insulator based
ones. The proposed bowtie HP nanoantenna is capable of monolithic
integration with laser and photodetector at optical communication
wavelengths. By using the finite-element method, it was
observed that the device can radiate and receive the optical field
with a gain of about 9 dB at frequency range of 180 to 220 THz.
In addition, the results showed that this device is expandable in
array structure. Antenna gains with two diverse array arrangements
of single row and square array were also determined.
