In this paper, the optical phase noise of the semiconductor laser is integrated with its electrical equivalent circuit (large signal model) to perform a system modeling approach. The model is employed in a heterodyne radio over fiber (RoF) system where two distributed feedback (DFB) lasers are used to generate a millimeter-wave (mm-wave) signal. An optical phase-locked loop (OPLL) is also introduced to reduce the phase noise on the generated mm-wave signal. With the developed model, phase noise contribution of individual lasers is evaluated even with more complex systems like OPLL in purely microwave simulator.

This paper presents a simulation approach of optical heterodyne systems by using the equivalent circuit representation of a distributed feedback laser (DFB) in the electrical domain. Since the electrical representation of the DFB laser is developed from the rate equations, its characteristics such as non-linearity, relative intensity noise (RIN), and phase noise can be predicted precisely for various biasing conditions. The model is integrated in a heterodyne radio over fiber (RoF) system where two DFB lasers are used to generate a millimeter-wave (mm-wave) signal. An optical phase-locked loop is also introduced to reduce the phase noise on the mm-wave signal. The optical phase noise contribution of individual lasers to the mm-wave signal is evaluated and compared with theoretical results. It is shown that the phase noise of the mm-wave is reduced considerably depending on the loop bandwidth and propagation delay. With the circuit simulation approach proposed, optical and mm-wave phase noises can be studied together with other circuit environments such as parasitic effects and driver circuits.

Photonic signal processing is a suitable alternative of electronics based processing for wideband frequency detection. We propose a novel technique for the detection of a wide range of frequencies based on photonic signal processing. The unknown frequency to be measured is used to modulate a tunable optical source by implementing single sideband suppressed carrier modulation. The modulated signal is combined with two fixed frequency optical carriers to perform heterodyne detection. The frequency of the tunable laser source is swept until significant power of the beat signal is observed after photodetection. A mathematical expression is presented that can be used to measure the frequency of the unknown electrical signal based on value of the center frequency of tunable laser source. The effect of increasing laser linewidth up to 100 MHz and instantaneous shift in laser center frequency up to 200 MHz has also been demonstrated. It has been shown that the proposed technique can measure almost any radio frequency by simply varying the frequency of the tunable laser source.
