“…However, during photodiode operation, photogenerated holes with slow drift velocity are always a major factor limiting speed. The 'slow' hole problem is eliminated in the InP-based UTC photodiode structure [ Normalized to spiral antenna output UTC (NBUTC) photodiodes [56][57][58][72][73][74], where only electrons with high drift velocity act as active carriers. Figure 6 shows conceptual band diagrams for p-i-n, UTC and NBUTC photodiodes.…”

“…This leads to a significant improvement in the effective carrier drift velocity of the photodiode during operation and excellent SCBP performance [28,70,71]. The major difference between the UTC photodiode and the NBUTC photodiode is the insertion of an additional p-type charge layer in the collector layer to control the distribution of the internal electrical field, which results in an over-shoot of the electron drift velocity even under high reverse bias voltage (-3 V) [56][57][58][71][72][73][74]. Figure 6(c) shows a conceptual band diagram for an NBUTC photodiode.…”

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.

“…The demonstrated transmitter comprises broadband front-end circuitry and the traditional waveguide-based horn antenna fed by a dipole-based structure for the realization of the directional radiation from the integrated photonic transmitter. The antenna feed structure is planar in nature and poised for easy integration with a near-ballistic uni-traveling carrier photodiode (NBUTC-PD) [11], [12] via a flip-chip bonding technique. Indeed, compared to the related past works [23]- [26], the proposed waveguide feed does not require any modifications to the waveguide connected to the horn antenna, as well as bond wires on the feed structure, which appears to be critical to a relatively easy and low-cost front-end implementation.…”

A high-speed -band integrated photonic transmitter is demonstrated. The presented integrated photonic transmitter is essentially developed with a near-ballistic uni-traveling-carrier photodiode integrated with a broadband front end through the flip-chip assembling technique. Technically, compared to our previous design, a -band bandpass filter is exploited to significantly increase the transmitter IF modulation bandwidth. The demonstrated integrated photonic transmitter has a flat broad IF modulation response, as well as a broad optical-to-electrical (O-E) bandwidth. Specifically, the variation of the normalized IF modulation response, ranging from dc to around 13 GHz, is within 3 dB, and the normalized 3-dB O-E bandwidth is about 24 GHz. On the other hand, an up to 20-Gb/s high data-rate wireless transmission realized with the presented transmitter is demonstrated. The integrated photonic transmitter is expected to find applications in high-speed radio-over-fiber communications.Index Terms-Front-end, photonic transmitter, radio-over-fiber (RoF), uni-traveling-carrier photodiode (UTC-PD), -band.

“…Compared with the UTC-PD-based optoelectronic 0741-3106/$26.00 © 2009 IEEE (OE) mixer [5], [6], our NBUTC-PD-based OE mixer has an improved modulation bandwidth even under a higher operation current, due to the elimination of the forward bias operation [5], [6].

Abstract-We demonstrate a novel W-band photonic transmitter mixer, which is composed of a planar quasi-Yagi radiator for feeding a WR-10 waveguide-based horn antenna and a nearballistic unitraveling-carrier photodiode. The module demonstrates reasonable coupling loss in terms of the millimeter-wave (MMW) power launched from the integrated radiator into the WR-10 waveguide. With the bias-modulation technique and an optical MMW source, we can successfully achieve a wireless data transmission of 2.5-Gb/s quadrature phase shift keying at a carrier wave frequency of 102.5 GHz with a transmission distance of over 2.3 m.Index Terms-High-power photodiode, optoelectronic (OE) mixer, photonic transmitter, quasi-Yagi radiator.
