Webdigital phase detection and a programmable digital proportional-integral-derivative (PID) loop in locking. The lock generates a narrow beat-note linewidth below 1Hz and low phase-noise of 0.03rad2 between the master and slave ECDLs. The lock proves to be stable and robust, and all the locking parameters can be set and optimized WebThe analysis for the two locking techniques studied in Chapters 2 and 3 has been com pleted in this Chapter and a new technique, combining optical injection locking and optical phase-lock loop systems, the optical injection phase-lock loop, has been presented.
