An economic and robust method to amplify optical frequency comb

VCSEL is injection-locked to one comb component with excellent single longitude mode performance. We tested the diodes without narrowly filtering the injecting comb and the VCSELs are able to sustain the injecting power. The low cost and low supply current of VCSELs furthermore reduce the complexity of amplifying the comb.Engineering, Electrical & ElectronicOpticsPhysics, AppliedEICPCI-S(ISTP)
