A novel fiber optic tap utilizing both surface relief microlenses and a
volume element was demonstrated. A fiber array bundle in a silicon V-groove
was also made to test diffractive lens coupling. The best measured single lens
coupling efficiency was 17%.
Future work in this area should be directed at making higher order phase
level lenses which exhibit much larger diffraction efficiencies. This should lead
to improvements in coupling efficiency. Alignment and packaging techniques
for maximizing coupling with the microlens arrays is another area for future
research.
