Paper Abstract

We consider a high power laser diode with significant external feedback from the entrance facet of a butt-coupled fiber. The effective reflectance of Fabry-Perot etalon, formed by the laser and fiber facets, undergoes deep modulation due to the change in the laser-to-fiber separation. This results in the variation of nonlinear lasing characteristics and the optical properties of the oscillation cavity, which leads to a significant wavelength tuning (up to 15 nm). The developed model successfully predicts experimental results. The longitudinal mode spectrum, tolerances and relative intensity noise are characterized as well.
