“…Although PM/FM-DD has been actively explored since the 1960's, as discussed in Section 2.3, we were the first to present complimentary linear-field demodulation as a simple ideal model for which to design discriminator filters. Although the early work of [33] had suggested a linear-field transmission ramp, they did not identify the use of balanced detection to cancel second harmonics or provide any guidance about the phase linearity of the filter. Later authors tried to linearize the slope of the power transmission instead, which we show is misguided (Section 2.6).…”

“…Except for the early work of [33], other "linearized" discriminators in the literature were designed such that the filter's optical intensity transmission ramped linearly with frequency offset from the carrier, rather than the field amplitude. These designs are not consistent with our theoretical link models.…”

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.

Abstract. We present an optical finite impulse response (FIR) filter design method. Based on crystal birefringence, an optical FIR filter can be designed to produce arbitrary spectrum output. A mathematic model of the optical FIR filter is introduced from the FIR theory. Details of the mapping relationship between an FIR filter and an optical filter are analyzed. A classical FIR filter design method is directly applied. After using the optical backward transfer method to implement the optical configuration, a design of a green/magenta broadband filter is discussed. The experiment results demonstrate that the theoretical simulation is in accordance with the experiment.
