Abstract
Single transverse and lateral mode InGaAs/GaAsP/InGaP 980 nm SPIN (spr ead index) ridge waveguide lasers (3 mu m x 750 mu m) with symmetric f ar fields of theta(perpendicular to) x theta(parallel to) = 17 degrees x 15 degrees, slope efficiency of eta(ext) = 0.9W/A and threshold cur rent of I-th = 24mA have been demonstrated. 90% coupling to singlemode lensed fibre and 52% direct buttcoupling to cleaved fibre has been ac hieved.
