Abstract
Two optical frequency combs (OFC) with total span of 8 THz have been realized and linked by injecting two laser beams into one OFC generator. Two lasers whose frequencies were separated by 2.6 THz were heterodyne phase-locked to link the two combs. The phase-locked loop bandwidth was 1 MHz and the phase error variance was estimated to be 0.08 rad/sup 2/.
