Self-Coherent Single-Sideband Signal Generation by Injection Locking of a 2-Section Laser Diode

We propose a low complexity transmitter of optical single-sideband modulation based on injection locking of a 2-section DFB laser to generate mutually-coherent tones. The scheme is experimentally demonstrated in 17-Gbd 16-QAM transmission with Kramers-Kronig reception.
