Non-resonant optical injection locking in quantum cascade laser frequency combs

Non-resonant optical injection locking in quantum cascade laser frequency combs

Optical injection locking of the repetition frequency of a quantum cascade laser frequency comb is demonstrated using intensity modulated near-infrared light at 1.55 µm, illuminating the front facet of the laser. Compared to the traditional electrical modulation approach, the introduced technique pr...
