Abstract

We report a comprehensive study of low-power, octave-bandwidth, single-soliton microresonator frequency combs in both the 1550-nm and 1064-nm bands. Our experiments utilize fully integrated silicon-nitride Kerr microresonators, and we demonstrate direct generation of these combs with widely available distributed Bragg reflector (DBR) lasers that provide less than 40 mW of chip- coupled laser power. Since microresonator soliton frequency combs are described completely by fundamental linear and nonlinear dynamics of the intraresonator field, we demonstrate the close connection between modeling and generation of octave-bandwidth combs. Our experiments advance the development of self-referenced frequency combs with integrated-photonics technology, and comb-laser sources with tens of THz bandwidths across the near infrared.
