ELECTRICALLY CONTROLLED OPTICAL OSCILLATOR FOR A SINGLE-SIDE-SUBCARRIER OPTICAL PHASE-LOCKED LOOP

摘要

An electrically controlled optical oscillator (4) for a single subcarrier optical phase-locked loop, which includes: an electrically controlled electrical oscillator (8) having an input, which receives an electrical driving input signal (VPDF), and an output, which supplies an electrical driving output signal (VEVCO) that has a frequency (FEVco) that is a function of the electrical driving input signal (VPDF); a continuous -wave laser source (9), which supplies an optical carrier (SOc); and an optical modulator (12), which has an optical input connected to the laser source (9) and receives the optical carrier (SOc) / an electrical input, which is connected to the output of the electrically controlled electrical oscillator (8) and receives the electrical driving output signal (VEVco) / and an optical output that modulates the optical carrier (SOc) with the electrical driving output signal (VEVCO) and generates an optical modulated signal (S2). The optical modulator (12) generates an optical modulated signal (S2) with single optical subcarrier.
