Microlenses for coupling junction lasers to optical fibers.
TL;DR: A novel photolithographic technique was used to make hemispherical and hemicylindrical microlenses, with diameters between 4 microm and 10 microm, from commercially available negative type photoresist that is transparent at ir laser wavelengths.

Integration of micrometer-sized polymer elements at the end of optical fibers by free-radical photopolymerization
TL;DR: A simple method of manufacturing micrometer-sized polymer elements at the extremity of both single-mode and multimode optical fibers is reported and it is shown that the tip geometry can be adjusted by the variation of basic parameters such as the geometry of the deposited drop and the conditions of drop illumination.

Light coupling from a stripe-geometry GaAs diode laser into an optical fiber with spherical end
TL;DR: The acceptance angle of a fiber is increased remarkably by forming the fiber end spherically as discussed by the authors, and the coupling efficiency increased in this way is observed to be 5.2 times as high as that of a previous method.
