Abstract :
Broad wavelength tuning under single-mode oscillation is achieved for a 1.5 ¿m range multi-electrode distributed feedback laser. The lasing wavelength can be tuned electrically, maintaining a stable single-mode oscillation without mode jumping. The tuning has reached over 20 ¿ under a noticeable condition of constant power (5mW), with a sufficient side-mode suppression ratio over 30 dB.
