Ultra-high power, low RIN and narrow linewidth lasers for C-band DWDM +100km fiber optic link

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.
