Abstract
En 中文
To realize high-power GaInAsP/InP pump lasers for Raman amplifiers, we propose a laser with a GaInAsP/InP electric field control layer that has high design freedom and is suitable for mass production. This laser structure realizes high power and low power consumption of Raman pump lasers with fiber output power exceeding 1 W at high temperature operation of 35 degrees C, and extremely low power consumption of 3.7 W at 55 degrees C with 0.5 W fiber output power is demonstrated. We also demonstrate that this laser structure is effective in achieving high-power fiber output power exceeding 0.78 W at 35 degrees C in the range from 1395 nm to 1547 nm for the application of broadband Raman amplification, which is a key technology for ultra-high-speed large-capacity optical transmission systems using digital coherent systems.
