Abstract :
Microlenses have been fabricated directly on the ends of optical fibres which demonstrate 90% (-0.45 dB) coupling efficiencies to semiconductor lasers. The lenses are made by laser micromachining a spinning fibre in a microlathe arrangement. Theoretically, it is possible to collect nearly 100% of the laser radiation with the aspheric lens design presented.
