This paper presents the first hybrid-integration assembly of a power amplifier (PA) monolithic microwave integrated circuit (MMIC) and a beam-steering leaky wave antenna (LWA) using an ultra-precise deposition (UPD) printed coplanar waveguide (CPW) interconnect operating in a broad sub-THz range of 220 GHz to 325 GHz. The hybrid assembly uses an InGaAs PA with a saturated output power of up to 14....Show More
We present photonics-driven high data rate IEEE 802.15.3d compliant terahertz (THz) communication links operated at a center frequency of 280 GHz. We analyze wireless data transmission within selected single and dual channels of the IEEE 802.15.3d and assess the outcomes through additional back-to-back (B2B) data transmission measurements and calibrated link budgets of the THz link. The system arc...Show More
We present a novel GCPW-to-WR3 E-plane transition for monolithic integration with InP-based THz UTC-PDs. The E-plane transition allows for coupling the optically generated THz signal through the THz UTC-PD vertically into a standard WR3 output. This approach enables compact chip-on-carrier packaging of the THz UTC-PDs. The electrical performance of the designed E-plane transition was numerically a...Show More
Photonic generation of millimeter- and terahertz-waves (30 GHz - 10 THz) has gained increasing interest and photodiodes have become key components in this regard. Among other photodiode technologies, the uni-travelling carrier photodiode (UTC-PD) has been a breakthrough in reaching high speed and high output power simultaneously. Consequently, UTC-PDs have been employed in numerous photonic applic...Show More
In this paper, we report on the integration of a photonic beam steering transmitter for the 5G26 GHz band. The transmitter, designed for fiber-to-the-antenna applications, is based on an optical polarization diversity receiver and a PCB leaky-wave antenna. Therefore, an integrated photoreceiver with polarization dependent couplers and high frequency waveguide photodiodes provides optoelectronic co...Show More
In this paper, we report a phase-sensitive photonic THz two-tone self-mixing imaging system, comprising a self-developed vertical illuminated triple transit region photodiode (TTR-PD) and a commercial square law Schottky barrier diode as THz emitter and THz detector, respectively. Using the two-tone self-mixing approach, the phase information of a device-under-test can be extracted by down-mixing ...Show More
