“…Although these photodetectors are mature and capable of achieving the high bandwidth required for mm-wave communications, their power handling capability may be limited. For higher power operation that may obviate the need for amplifiers, and for scalability to even higher (potentially terahertz) frequencies, unitraveling-carrier photodiodes (UTC-PDs) are particularly attractive [24]. These photodiodes provide sufficient power to directly drive integrated antennas and can be hybrid integrated with low-loss waveguides based on SiPh or PLC technology.…”

This article presents recent developments in millimeter-wave communications architectures featuring broadband photonic signal generation, up-conversion and down-conversion, as well as true-time-delay photonic steering of millimeter-wave arrays. These developments will support future high-capacity millimeter-wave wireless communications by enabling broadband signals to be generated and converted between baseband and millimeter-wave carrier frequencies without electronic heterodyne systems and by permitting the use of true-time-delay beamsteering in millimeterwave array apertures.

“…Superconductor-insulatorsuperconductors (SIS), hot electron bolometers (HEB) and Schottky diode mixers are common detectors [8]. Recently, the UTC-PD has been demonstrated as an optically pumped mixer at frequencies up to 600 GHz [17]. However, this demonstration used an unmodulated signal with only 100 Hz of IF detection bandwidth which is not enough for communications purposes.…”

We present the first demonstration of a wireless transmission link based on uni-traveling carrier photodiodes (UTC-PDs) as transmitter and receiver. In this demonstration, a UTC-PD was used at the transmitter to generate a 1-Gbps ON-OFF keying data signal at a carrier frequency of 61.3 GHz by heterodyning two modulated optical tones originating from an optical frequency comb system. The generated electrical heterodyne signal was transmitted, using a 25-dBi gain parabolic antenna. An identical antenna was used to detect the signal at the receiver, followed by an optically pumped UTC-PD mixer to down-convert the received RF signal to an intermediate frequency of 6.3 GHz, which was subsequently amplified and acquired by a real-time oscilloscope for offline processing. The recovered data showed an open eye diagram, and a bit error rate of the order of 10-5 was measured. The receiver UTC-PD was characterized in terms of its conversion loss and noise figure (NF), and the overall NF of the receiver was measured at 21.5 dB.

“…It has already been shown that an UTC-PD can be used as an OPM at frequencies up to 600 GHz [9], but these demonstrations were done within a kHz bandwidth [7,10]. In this paper, we demonstrate, for the first time, an OPM based on UTC-PD to down-convert a wireless RF signal modulated with 1 Gbaud quadrature phase shift keying (QPSK) data occupying a bandwidth of 1.35 GHz and centered at 33.5 GHz.…”

Abstract-This paper presents the first demonstration of an uni-travelling carrier photodiode (UTC-PD) used as a receiver of a wirelessly transmitted quadrature phase shift keying (QPSK) signal. In this demonstration, a 1 Gbaud QPSK signal centered at 33.5 GHz was transmitted over a wireless distance of 1.4 m. At the receiver, an UTC-PD is used to down-convert the RF signal to an intermediate frequency (IF) of 9.5 GHz by mixing the RF signal with a heterodyne signal at 24 GHz. The down-converted signal is captured by the real time scope for further digital signal processing. The error vector magnitude (EVM) of the demodulated signal was measured to be 18%, which corresponds to a bit error rate (BER) of 10 -8 .
