  • Abstract
    A novel fabrication method for hemiellipsoidal microlenses formed on fibre ends is proposed, for efficient coupling from laser diodes into single-mode fibres. The method permits the realisation of microlenses with the required ellipticities to match the fields of lasers and fibres. A very low coupling loss of 2.65 dB has been achieved.
