“…With this NBUTC device we have demonstrated an SCBP of over 4,070 mA GHz [58], and a NBUTC photodiode with a linear cascade structure has been reported to have an SCBP of as high as 7,500 mA GHz, the highest achieved so far [56,57]. The excellent performance of UTC and the NBUTC photodiodes in terms of speed and saturation power means that high-performance photonic transmitters with an end-fire or broadside radiation pattern [24,25,30,75,76] and operating frequency of 0.1-1 THz can be realized, along with a much higher output power (>20 dB) compared with p-i-n [77] and LTG-GaAs-based photonic transmitters [70]. Figure 7 shows a UTC photodiode-based photonic transmitter with a broadside (patch) antenna [76] and end-fire (tapered slot) antenna [30] for the excitation of WR-10 and WR-8 rectangular waveguide-based horn antennas.…”

T he most useful wireless communication band is located in the frequency range of 0.3-3.5 GHz for reasons of compact antenna size, low propagation loss and good penetration through buildings [1]. However, wireless carrier frequencies are being pushed higher due to emerging high-bandwidth applications, which include next-generation smart cell phones [1] and wireless linking for three-dimensional super high-definition television [2]. As a result, the millimeter-wave (MMW) bands at 60 (V-band), 120 (D-band) and even higher than 300 GHz are beginning to attract attention due to their 'unlicensed' usage [2][3][4][5][6][7][8].Several key front-end components have been developed employing the already mature silicon-based complementary metal-oxide-semiconductor (CMOS) integrated-circuit (IC) technology for wireless communication in the V (50-75 GHz) and W (75-110 GHz) bands or even higher operating frequencies for wireless communication [9]. Recently, a 60 GHz CMOS transceiver module [10] and system comprised of antennas, 60 GHz power amplifiers, local oscillators and baseband ICs has been commercially developed by SiBEAM (USA). In addition, advanced InP-based high electron mobility transistors (InP-HEMTs) and heterojunction bipolar transistors have been used to develop some high-speed ICs and key components that operate at 125 GHz [11,12] or greater than 300 GHz [13,14] for >1 Gbit s -1 wireless communication systems.However, MMW signals suffer substantial propagation loss in free space [8]. This problem and their inherent straight-line path of propagation affect connections and synchronization between the different parts of the whole communication system [15]. A promising solution to overcome this problem is the radio-over-fiber (RoF) technique [3,4,16,17], in which the MMW local-oscillator signal and data are both distributed through a low-loss optical fiber and only radiated over the last mile to the end user. Figure 1 shows a schematic representation of this approach, illustrating the motivation and working principles of two MMW-over-fiber communication systems. Figure 1(a) shows the additional electrical-to-optical (E-O) and optical-to-electrical (O-E) conversion processes used in the central office and base station, respectively. The optical MMW signal is distributed remotely through a low-loss fiber from the central office to several base stations, effectively eliminating the huge propagation loss of the MMW signal that occurs in an electrical transmission line or free space.

“…Radioastronomical signals from the universe have been successfully observed using a 98-GHz photonic LO [75]. Use of the photonic LO in the SIS mixer system is the best combination, since the SIS mixer requires an LO power as low as a few 10 nW, that has been already achieved with the use of RF photodiodes [76]. Another advantage of the photonic LO in spectroscopic measurement systems is their wide tunability.…”

There has been an increasing interest in photonic generation of RF signals in the millimeter-wave (30 GHz ∼ 300 GHz) and/or terahertz-wave (0.1 THz ∼ 10 THz) regions, and photodiodes play a key role in it. This paper reviews recent progress in the high-power RF photodiodes such as UniTraveling-Carrier-Photodiodes (UTC-PDs), which operate at these frequencies. Several approaches to increasing both the bandwidth and output power of photodiodes are discussed, and promising applications to broadband wireless communications and spectroscopic sensing are described.Photodiode chip is bonded to the substrate with the antenna.
