A new concept for photonic transmitter (PT) is presented for radio-over-fiber (RoF) wireless communication in E-band frequencies. The device features a high power and high frequency photodiode (PD) integrated with a wideband and high gain tapered slot antenna with a built-in biasing network on an RF laminate. Presented approach allows for simpler and low loss optoelectronic integration. The full-wave...
In this paper, a proof-of-concept sub-THz detector for its use in radio telescopes is presented. The detector is intended to work at room-temperature and to be suitable for cosmic microwave background B-mode polarization measurements, so a high sensitivity photon-countig receiver is required. The proposed detector is a practical arrangement of several receivers, each one working on the principle of...
In this manuscript, we present a new antenna topology applied to the so called THz gap, based on using a dielectric rod antenna avoiding the use of the classical lens for collimating the emitted/received power. The scope and future perspective of the manuscript is beyond this idea: we develop this topology with the perspective of being the optimum antenna system to be coupled in a THz waveguide easy...
