MULTIPLE KERR-FREQUENCY-COMB GENERATION USING DIFFERENT LINES FROM A REMOTE KERR COMB

摘要

Methods, systems, and apparatus for generating Kerr frequency combs. The system includes a continuous-wave pump laser to provide a master comb pump. The system includes a microresonator that generates a master Kerr frequency comb using the master comb pump. The system includes a splitter that splits the master Kerr frequency comb into multiple CW comb lines including a first comb line used to transmit a data signal and a second comb line used as a slave comb pump. The system includes a combiner that is configured to combine the first comb line and the second comb line to produce a combination of a data channel and CW comb line. The system includes a second demultiplexer that extracts the second comb line that is used as the slave comb pump. The system includes another microresonator that uses the second comb line and generates a slave Kerr frequency comb.
