Laser & Photonics Review

An external‐cavity diode laser for 1550‐nm wavelength is reported with ultra‐low noise, high power coupled to a fiber, and fast tunability. These characteristics enable the generation of an optical frequency comb in a silica micro‐resonator with a single‐soliton state. Neither an optical amplifier nor a modulator is used in the experiment. This demonstration greatly simplifies the soliton generation setup and represents a significant step forward to a fully integrated soliton comb system.
