Abstract
We present an optical phase locked loop based on sub-carrier modulation and designed using commercial optical components. In principle the output of a continuous-wave laser is subcarrier modulated by a common LiNbO3 MachZe-hender driven by an electrical voltage controlled oscillator. The proposed architecture is used as optical receiver for homodyne coherent detection of ultra-dense WDM 2.5 Gbps 2-PSK signals with 6.25 GHz spacing. This method offers the potential for providing many closely spaced multigigabit channels and enables coherent lightwave technology to become commercially viable.
