ABSTRACT:
A semiconductor laser diode is optically coupled to an electro-optic phase modulator and an electrical control signal is applied to the phase modulator to modify its optical gain or loss and its real refractive index, to in turn alter the optical length of the modulator and shift its resonant wavelengths. The result is to tune the laser diode. A facet of the laser diode is anti-reflection coated to minimize interface loss between the laser diode and the phase modulator.
