Graphene‐Coupled Terahertz Semiconductor Lasers for Enhanced Passive Frequency Comb Operation
Abstract Optical frequency combs, consisting of well‐controlled equidistant frequency lines, have been widely used in precision spectroscopy and metrology. Terahertz combs have been realized in quantum cascade lasers (QCLs) by employing either an active mode‐locking or phase seeding technique, or a...
