Unidirectional optical frequency comb injection of multi-section quantum well lasers — •Jan Lautenschläger1, Christoph Weber1, Dominik Auth1, Andreas Klehr2, Andrea Knigge2, and Stefan Breuer11Institute of Applied Physics, Technische Universität Darmstadt, 64289 Darmstadt, Germany — 2Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik, Gustav-Kirchhoff-Straße 4, 12489 Berlin, Germany

Unidirectional optical injection is a versatile concept to transfer optical properties from a master optical frequency comb laser into a slave optical frequency comb laser. Thereby the optical frequency comb stability of the slave device could be improved and the optical comb broadened. By studying optical injection of two similiar multi-section monolithic quantum-well lasers emitting at 1070 nm with different biasing schemes, an optical frequency comb generated by passive mode-locking is injected into a single-mode laser and the optical and radio-frequency properties of the light emitted by the slave laser are studied. We identify an optical frequency comb generation in the slave device and analyze regimes of injection locking.
