Wavelength-maintaining Fabry-Perot Laser Diode and optical transmitter including same

摘要

A wavelength tracking Fabry-Perot Laser Diode (F-P LD), and an optical transmitter including the same are disclosed, the wavelength keepable F-P LD including a gain section configured to provide and modulate a gain using an injected first current; and a phase shift/modulation section configured to vary wavelength relative to oscillation mode of light advanced from the gain section by injected second current or voltage and to modulate phases.
