摘要
Class-AB techniques are analyzed as a means to minimize the noise associated with the residual carrier in analog optical links. A bound for shot and intensity noise is derived and compared to previously reported measurements. It is found that for an ideal modulator transfer function (Class B), a substantial improvement in shot-noise limited spur-free dynamic range (e.g., 11.7 dB at 10% modulation) can be realized.
