Abstract

The spectral linewidth of continuously wavelength tunable laser diodes has been significantly reduced by the buried facets technique. Embedding the λ_g = 1.3μm InGaAsP tuning region of a λ = 1.55μm tunable twin-guide distributed feedback laser entirely in high-bandgap InP suppresses the electronic 1/f noise by more than 10dB, yielding a spectral linewidth up to a factor of two smaller during tuning.
