  • Abstract
    The epitaxial layers of an lnGaAsP laser structure have been engineered to obtain a transverse mode size of 3.1 μm and a FWHM transverse divergence to 22° while still retaining single mode operation. Ridge lasers based on this structure demonstrate 32% butt coupling efficiency to single mode fibre
