We present a comprehensive study of uni-travelling carrier photodiode impedance and frequency photo-response supported by measurements up to 110 GHz. The results of this investigation provide valuable new information for the optimisation of the coupling efficiency between UTC-PDs and THz antennas. We show that the measured impedance cannot be explained employing the standard junction-capacitance/series-resistance concept and propose a new model for the observed effects, which exhibits good agreement with the experimental data. The achieved knowledge of the photodiode impedance will allow the absolute level of power emitted by antenna integrated UTCs to be predicted and ultimately maximised.

“…In photodiode technology, devices with a 3 dB bandwidth in excess of 100 GHz are available from Finisar, a partner in FIWIN5G (formerly U 2 T). High frequency and high output power PDs are one of the key elements in today's optical RoF links with high performance PDs actively investigated within the project [18]. Key objectives of the current research in high performance PD development is to enhance the operational frequency limitations and simultaneously to achieve high radio frequency (RF) power saturation levels without affecting the PD bandwidth.…”

Arrayed waveguide grating multi-wavelength lasers have been shown to provide simultaneously multiple wavelengths. In this work we report the characteristics of the heterodyne signal in the millimeter-wave range. The optical linewidth measured from the modes generated by the different channels can be as narrow as 120 kHz. We present for the first time the beat note obtained from mixing two channels onto a high speed photodiode, demonstrating a narrow linewidth of 250 kHz, which is to the best of out knowledge the narrowest beat-note measured from a free running monolithic semiconductor dual wavelength source working on the 1,550 nm wavelength range.
