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

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.
