We report advancement in C-band DWDM lasers with ultra-high coupled optical power (>100mW) operated at 500mA. The laser also showed excellent RIN (≥−168dB) and narrow linewidth (<25kHz) suitable for +100km transmission. Life test (>3000hr) performance was robust.
We have developed 1550 nm DWDM lasers with ultra-high optical power (140 mW) operated at 400 mA. The laser also showed excellent RIN ( ges-161 dB) and narrow linewidth (115 kHz) suitable for 100 km transmission. Life test ( > 8800 hr) performance was robust.
Quantum-dot (QD) lasers exhibit many useful properties such as low threshold current, temperature and feedback insensitivity, chirpless behavior, and low linewidth enhancement factor (alphaH-factor). Although many breakthroughs have been demonstrated, the maximum modulation bandwidth remains limited in QD devices, and a strong damping of the modulation response is usually observed pointing out the...
