Outline of Final Research Achievements

Ultra compact wavelength tunable laser diode with a semiconductor optical amplifier and a silicon photonics wavelength tunable filter was developed. A 99 nm wide wavelength tunable range, less than 15 kHz narrow spectral linewidth and more than 40 mW high output power were respectively achieved. The 1.2 um wavelength tunable laser with quantum dot optical amplifier was also developed.
