Wavelength bistability in two-section mode-locked quantum-dot diode lasers



Mingming M. Feng, N. A. Brilliant, Steven T. Cundiff, Richard Mirin, Kevin L. Silverman


We report a two-section mode-locked quantum dot laser with an emission wavelength that is bistable with respect to applied bias on the saturable absorber region. The two stable lasing wavelengths for this device are 1173 nm and 1166 nm with a power contrast ratio of over 30dB. The optical power and pulse width (6.5 ps) are almost identical in the two lasing modes under optimized conditions. The operation of this laser can be explained by the interplay of the spectral-hole burning and the quantum-confined Stark effect.
