Abstract

High-power single-mode 980nm pump lasers are the key components in optical fiber amplifier. Thermal management for the telecom applications is a key design parameter for both package and system level. In this paper, based on the designed structural and material parameters of Epi-down bonded uncooled 980nm laser, the heat distribution of Epi-down bonded uncooled pump laser was simulated using the finite element method, and the photoelectric properties of designed and packaged module were tested. A fiber output power of 200mW was achieved for the Epi-down bonded uncooled 980nm laser with fiber Bragg grating, and module can work steadily over a wide temperature range of 0~70°C, with a small wavelength shift of 0.2nm, along with a FWHM less than 1.1nm, and a SMSR of more than 45dB.
