“…What's worse is the noise figure of this particular link, which is 18.5 dB, compared to 1 dB for the electronics case. Assuming a shot-noise limited receiver, the noise figure is calculated by using [17] N F = 10 log 10 2eV where V π is the modulator half-wave voltage, K is Boltzmann's constant, T is the system temperature (300 K), Z in is the input impedance of the system, typically 50 ohms. The noise figure is heavily influenced by the inefficiency of the e-to-o transducer, given by large V π .…”

“…The filters are called phase and frequency discriminators. The demodulation process is called phase-modulation or frequency-modulation direct-detection (PM-DD or FM-DD [31]), filter-slope detection, or interferometric detection [17]. The architecture for the PM-DD and FM-DD links consists of a modulation source, discriminator filters, and balanced detectors.…”

Photonic systems that transmit and process microwave-frequency analog signals have traditionally been encumbered by relatively large signal distortion and noise. Optical phase modulation (PM) and frequency modulation (FM) are promising techniques that can improve system performance. In this dissertation, I discuss an optical filtering approach to demodulation of PM and FM signals, which does not rely on high frequency electronics, and which scales in linearity with increasing photonic integration. I present an analytical model, filter designs and simulations, and experimental results using planar lightwave circuit (PLC) filters and FM distributed Bragg reflector (DBR) lasers. The linearity of the PM and FM photonic links exceed that of the current state-of-the-art.

“…Recently, the envelope detection technique is a promising option to simplify the RoF system since no RF down-conversion is needed at the receiver compared to the conventional RoF system [10]. On the other hand, phase-modulated RoF links present several advantages over the intensity modulated links, such as no need for dc bias, better link gain, and linearity [11].…”
