Abstract

The dynamics of monolithically integrated amplified feedback lasers (AFL) is investigated through numerical simulation and experimental verification. The period-doubling route to chaos and high-frequency microwave generation are demonstrated through simulation. Then, we design and fabricate monolithically integrated AFLs. Mappings of dynamic states and oscillation frequency in the parameter space of phase section current I_P and amplifier section current I_A are depicted. For relative small I_A, the period doubling evolution to chaos is presented with the increase of I_P. For the relative large I_A, a high-frequency mode-beating (M-B) pulsation can be observed under suitable value of I_P. The oscillation frequency of period-one is about 10 GHz and the frequency of M-B pulsation is over 40 GHz for the device with a total length of 780 μm.
