Paper Abstract

Slab-coupled waveguide laser was theoretically analyzed by E. A. J. Marcatili [1] in the 1970's, based on which, we recently demonstrated a high power slab-coupled waveguide laser with buried hetero-structure. The laser lases around 1525.5 nm, with 3.4 μm*4.4 μm (FWHM) spatial mode shape. With improved current blocking mechanism, the output power reaches 326mW per facet, the coupling efficiency to the single mode fiber (SMF) is 80%, the horizontal and vertical far field angles are 10°, 18° respectively. Electron blocking layer will be implemented to improve internal quantum efficiency. Epi-side down bonding will be used to improve heat dissipation and output power.
