We demonstrate W-band photonic transmitters-mixers, which are composed of near-ballistic-uni-traveling-carrier-photodiodes and quasi-Yagi antennas without integrating Si-lens.

In this study, we demonstrate wireless binary phase-shift keying (BPSK) and quadrature phase-shift keying (QPSK) data transmission at the-band by use of bias modulation on photonic transmitters-mixers, which are composed of near-ballistic uni-traveling-carrier photodiodes and quasi-Yagi antennas without the integration of an Si-lens. By use of such a device and a novel optical millimeter-wave source with octupling optical frequency, we can successfully achieve 1.25-Gb/s BPSK and 0.625-Gb/s QPSK data-transmission at 105 GHz with 5-GHz intermediate-frequency signals.

We analyze the dynamic behaviors of a novel device, i.e., cascaded high-speed laser power converters (LPCs), which can detect the direct-current (dc) component of an incoming highspeed optical data stream and efficiently convert its dc component to dc electrical power. By utilizing a p-type photoabsorption layer in our LPC, the problem of slow-motion holes can be eliminated, and only the electrons act as the active carriers. We can thus achieve high-speed performance with the LPC under forward-bias operation with a small electric field inside. Furthermore, according to our modeling and measurement results, there are a significant alternating-current capacitance reduction and an electron-trapping effect at the interface between the absorption and collector layers with a significant degradation in the carrier drift velocity. These become more serious with the increase in optical pumping power and forward-bias voltage and truly limit the net optical-to-electrical (O-E) bandwidth of the device. In order to overcome such a transient-time-limited bandwidth and further increase the maximum dc output voltage of the LPC, we connect two single LPCs in series (cascade). Error-free data detection of 10-Gb/s and an O-E dc power-generation efficiency of 21.1% can be achieved simultaneously at a wavelength of 850 nm by the use of such two cascaded LPCs.

A W-band photonic transmitter-mixer, constructed by integrating a planar quasi-yagi radiator for feeding the WR-10 waveguide-based horn antenna and a near-ballistic uni-travelingcarrier photodiode, is used with a mode-locked fiber laser to obtain 2.5-Gb/s impulse-radio (IR) wireless data transmission at around a center frequency of 100 GHz. The bias-modulation technique provides less jitter and a longer maximum transmission distance compared with the technique of modulating the optical pulse train using an electrooptics modulator. Using the bias-modulation technique, we achieve a 2.5-Gb/s IR wireless data transmission.

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 near-ballistic 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.
