Intermode beat frequency and line-width stabilization of a 1 mm long self mode-locked
frequency comb quantum dash laser emitting at 1535 nm by external all-fiber based single-
cavity optical self-injection time-delay control is presented. Self-injection optical delay tuning
is conducted by piezo-crystal single-mode fiber stretching. An intermode beat frequency
control by 2 MHz and an intermode beat frequency line width reduction from 67 kHz to
approximately 900 Hz is achieved. The experimental results are confirmed by an …

Intermode beat frequency and line-width stabilization of a 1 mm long self mode-locked frequency comb quantum dash laser emitting at 1535 nm by external all-fiber based single-cavity optical self-injection time-delay control is presented. Self-injection optical delay tuning is conducted by piezo-crystal single-mode fiber stretching. An intermode beat frequency control by 2 MHz and an intermode beat frequency line width reduction from 67 kHz to approximately 900 Hz is achieved. The experimental results are confirmed by an independent free-space stabilization experiment and stochastic time-domain modeling.
