Abstract :
The authors propose a simultaneous frequency control scheme for multiple DBR lasers in a virtual wavelength path (VWP) cross-connect system. The frequencies of eight DBR lasers are switched and held to the 100 GHz-spaced grid anchored at 193100 GHz, and stabilized to within 100 MHz for 12 h.
