SOA integrated EA-DFB laser and driving method thereof

摘要

The present invention relates to an SOA integrated EA-DFB laser in which a DFB laser unit, an EA modulator unit, and an SOA unit are monolithically integrated on the same substrate and a method of driving the SOA integrated EA-DFB laser, wherein the EA-DFB laser is connected to an optical transmission module From the maximum injection current to the DFB laser part of the EA-DFB laser that is allowed when mounted, the reduction amount I_DFBThe power consumption which does not exceed the sum of the power consumption which can be reduced by the DFB laser part of the SOA integrated EA-DFB laser and the power consumption reduced by the EA modulator part of the SOA integrated EA-DFB laser Of the current I_SOAIs injected.
