Influence of optical amplifier on inter-satellite microwave photonics links employing a low-biased Mach-Zehnder modulator

An exact analytical expression of signal-to-noise ratio (SNR) for inter-satellite microwave photonics links using a low-biased Mach-Zehnder modulator, and with both an optical booster amplifier and a preamplifier, is derived with the method of Bessel expansion and Graf's addition theorem. It is...
