ABSTRACT:
Longitudinal mode coupling is used in an injection laser to achieve single longitudinal mode output. By imposing a to small amplitude sinusoidal signal to modulate the laser injection current, this coupling is provided by producing sidebands on the photon distributions of the longitudinal modes.
