| Abstract(in English) | High power 980 nm laser diodes (LDs) are used as pumping sources of EDFAs (Erbium Doped Fiber Amplifiers). Reductions of cost and power consumption on EDFAs are very important for access or metropolitan applications. System construction without FBGs(Fiber Bragg Gratings) and TECs(Thermal Electric Coolers) is strongly required. Therefore, high power 980 nm LDs with small lasing wavelength changes during various operational conditions are greatly requested in these systems. We have proposed a new suppression technique on wavelength change by means of facet coatings for 980nmLDs. Less than one-third reduction of lasing wavelength change was realized by this method. Moreover, the proposed LDs possess more than 350 mW output power even at 95℃ and good reliability under a condition of 50℃,700mA-ACC(Automatic Current Control). |
