[IEEE 2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting - Atlanta, GA, USA (2019.7.7-2019.7.12)] 2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting - Full D-band Coplanar to Rectangular Waveguide Transition for UTC-PD Application
摘要： This paper presents a broadband coplanar waveguide (CPW) to rectangular waveguide transition for unitraveling carrier photodiode (UTC-PD) THz source application. The four step Chebyshev ridge waveguide is used to transform the quasi-TEM mode of the CPW to the TE10 mode of the rectangular waveguide, and to widen the transition bandwidth. Simulated results demonstrate that the proposed CPW to waveguide transition covers the whole D band (110-170 GHz), and achieves a wider fractional bandwidth of 43% and lower insertion loss of 0.5 dB.

[IEEE 2019 International Topical Meeting on Microwave Photonics (MWP) - Ottawa, ON, Canada (2019.10.7-2019.10.10)] 2019 International Topical Meeting on Microwave Photonics (MWP) - An Antenna-integrated UTC-PD based Photonic Emitter Array
摘要： In this paper we present a photonics-based wideband emitter module, using two uni-travelling carrier photodiodes coupled to a pair of high gain planar antennas, reporting a two-element array operating in the 50 to 120 GHz frequency range. This antenna array provides a maximum gain of 15.9 dBi with side-lobes less than -15 dB. The measurements show a record 3-dB bandwidth of 45 GHz, covering three waveguide bands (V, E and F). Moreover, a combined peak radiated power of -6.4 dBm (214 (cid:2)W) at 75 GHz is also achieved. The scalable design presented allows for realization of photonic phased antenna array.

Design of Bias-Free Operational Uni-traveling-Carrier Photodiodes by Transient Simulation for High-power Pulsed Millimeter-Wave Signal Generation in the Sub-THz Regime
摘要： In this paper, bias-free operational uni-traveling-carrier photodiodes (UTC-PDs) for high-power pulsed millimeter-wave signal generation in the sub-terahertz regime are designed and investigated. The reliability of the physics-based transient simulation is first demonstrated by comparing with reported experimental results. Then, the epitaxial layers are analyzed and optimized through transient simulation for bias-free operation and high-power pulsed millimeter-wave signal generation. The performance between original and optimal structure is compared under excitation of pulse train and sinusoidal optical signals. The results show that the peak output power of the modified UTC-PD under 100-GHz, 200-GHz, and 312.5-GHz pulse train excitation is 4.685 dBm, 1.128 dBm, and ? 4.653 dBm, improved by 2.05 dB, 5.15 dB, and 9.36 dB, respectively.
