Octave-Spanning Frequency Comb Generation in a MicroresonatorPascal Del’Haye1, •Tobias Herr1, Emanuel Gavartin2, Ronald Holzwarth1, and Tobias Kippenberg1,21Max-Planck-Institut für Quantenoptik, 85748 Garching, Germany — 2École Polytechnique Fédérale de Lausanne, CH 1015, Lausanne, Switzerland

We demonstrate for the first time the generation of an octave-spanning optical frequency comb via four-wave mixing in a fused silica microresonator. The microresonator is resonantly pumped via a tapered optical fiber with an amplified tunable diode laser (continuous-wave) at a pump power of 2.5 Watt. The generated frequency combs extend from 990 nm to 2170 nm, covering more than a full octave and are continuously tunable over more than 1 THz by changing the pump laser frequency. Octave spanning frequency combs directly generated in a monolithic microresonator are an important step towards fully self-referenced optical frequency combs on a chip.
