Generator systems for optical subcarriers based on ring resonator in series and parallel with phase modulation

Abstract

This work presents four systems for generation of optical subcarriers in the C-band in optical communications, based on serial and parallel amplified optical ring resonator with phase modulation and 10 GHz spectral spacing between subcarriers. The systems were numerically simulated and were able to generate between 83 to 145 subcarriers with output power levels of −5 to 26 dBm for an input power of 0 dBm and with flatness of 1.4 to 8 dB with a minimum OSNR of 30 dB.
