  • Abstract
    Single transverse and lateral mode InGaAs/GaAsP/InGaP 980 nm SPIN (spread index) ridge waveguide lasers (3 μm×750 μm) with symmetric far fields of Θ⊥×Θ|| =17°×15°, slope efficiency of ηext=0.9 W/A and threshold current of Ith=24 mA have been demonstrated. 90% coupling to singlemode lensed fibre and 52% direct buttcoupling to cleaved fibre has been achieved
