“…Frequency up or down conversion using GaAs metalsemiconductor-metal photodetectors (MSM-PD) [4], InGaAs p-i-n photodiodes [5] or Si avalanche photodiodes (APDs) have been reported [6,7]. However, the optoelectronic mixers based on theses photodetectors require output signal amplification to compensate conversion loss and it is not an easy task to integrate these photodetectors with necessary electronic circuits in a cost-effective manner.…”

We present millimeter-wave optoelectronic mixers based on Si photodetectors fabricated by the standard 130 nm complementary metal-oxidesemiconductor (CMOS) process. The photodetector and optoelectronic mixer characteristics are investigated in order to optimize their performances. Using the avalanche process in photodetectors at high reverse bias voltages, efficient optoelectronic mixing with low conversion loss at 30 GHz band is obtained. In order to demonstrate the feasibility of applying this mixer for Radio-on-fiber (RoF) applications, detection and frequency up-conversion of optical 5 MS/s, 16 quadrature amplitude modulation (QAM) signals into the 30 GHz band is successfully performed. We believe this is the first report of using CMOS-compatible photodetectors for RoF applications.Index Terms -Avalanche process, CMOS compatible photodetector, microwave photonics, optoelectronic mixer, Radio-on-fiber systems.

“…On the other hand, a method of frequency-mixing detection by the use of the nonlinearity of the optical detector has been introduced to realize super-high-speed optical receivers [5][6][7][8][9][10][11]. In this case, the receiving device (detector) is used simultaneously as an optical detector and as an electronic mixer.…”

“…This concept was first introduced by Davis and Kulczyk [5,6] who used the nonlinearity of the multiplication factor of the APD for frequency conversion and demonstrated improvement of the SNR. Seeds and Lenoir [7] developed a more general multiplication model for the APD and discussed the conversion loss and the noise properties. Nakajima and Kawabata [9] proposed that this method might be employed in demodulation of super-high-speed optical signals.…”

The design principle of an optical receiver for super-highspeed signal demodulation using an avalanche photodiode (APD) as both the photodetector and the electronic mixer (mixing detection) is presented. A simple theory is provided to evaluate the signal and noise properties with frequency-down conversion. Expressions for the signal to noise ratio (SNR) and the receiver sensitivity are given. The SNR and the receiver sensitivity for mixing detection are dependent on both the local oscillator voltage and DC bias voltate of the photodiode. There is an optimal condition (an optimal local oscillator voltage and an optimal DC bias voltage) to maximize the SNR or to minimize the receiver sensitivity for a given APD. A comparison between mixing detection and direct detection is presented and the results show that the optimal bias voltage of the APD for best SNR and receiver sensitivity for mixing detection is less than that for direct detection, making for more stable operation. The optimal design of a receiver for direct detection is only related to the APD multiplication factor, whereas for mixing detection it is related to this factor and its derivatives.

It is shown that even if the modulating frequency of a light is too high for direct detection, the signal can be extracted by frequency conversion at the same time as the detection by means of the nonlinearity of the APD. When this frequency conversion detection is applied to an optical receiver, the detection bandwidth can be increased while the configuration of the optical detection circuit and the signal processing in the subsequent stages are simplified. A fundamental analysis is carried out with an APD which is confirmed experimentally.
