Jitter in analog optical links using a quadrature-biased Mach-Zehnder modulator

초록

Characteristics of jitter have been investigated in a 10-GHz analog optical link using a quadrature-biased MachZehnder modulator followed by an erbium-doped fiber amplifier (EDFA) and a PIN photodiode. For the case of low optical input power, jitter varies inversely with input power, indicating the thermal noise limited characteristic. For high input optical power, jitter saturates at a minimum for different RF power levels for the configuration without EDFA. For the configuration using EDFA, jitter is also inversely proportional to EDFA gain but shows different minima for different input optical power with output power fixed by adjusting EDFA gain because of amplified spontaneous noise noise.
