Abstract :
A wavelength-tunable, single-frequency GaInAsP-InP laser diode using an intracavity electrooptic LiNbO3 crystal as the wavelength selective component is discussed. Wavelength tuning is achieved by applying a driving voltage on the crystal electrodes. First results indicate a tuning rate of 1 GHz/V over a tuning range of about 4 nm. This performance was obtained using a nonoptimized X-cut, Z-propagating LiNbO3 crystal. A potential tuning rate of 6.5 GHz/V is possible with reasonable improvements
