    Optical frequency combs have emerged as an important tool for numerous applications in time-frequency metrology, spectroscopy, microwave generation, and data communications.  Recent work has shown that such combs can be generated on a photonic chip using lasers with milliwatt power levels.  I will discuss the underlying physics of such combs and their potential technological applications.
