ABSTRACT:
A hybrid laser arrangement is disclosed which is capable of providing an essentially uniform FM response and a relatively narrow linewidth signal, suitable for FM applications. The uniform FM response is obtained by inducing inhomogeneous linewidth enhancement through control of the bias currents applied to separate gain sections of a two-electrode Fabry-Perot device. Coupling of the two-electrode device to a narrowband resonant optical reflector provides for an extremely narrow signal linewidth.
