Evolution of Rod Antennas for Integrated Terahertz Photonics

摘要: Integrated terahertz photonics has emerged as a viable option for routing and processing signals with high efficiency broad bandwidth. This can be implemented by using photonic crystal waveguides entirely made of float-zone intrinsic silicon slab that exceptionally low loss waves. A challenge presented here is to couple guided waves in this integrated platform free-space It imperative the coupling antennas must have loss, bandwidth, gain, part platform. Here we present an evolution antenna designs from single dielectric rod array satisfy all these requirements. All are onto same used waveguiding.
