Quasi-toric planar microlenses for oblique-incidence light beams

摘要

Novel quasi-toric planar microlenses (PML's) suitable for planar optics ape proposed. The PML's have elliptical apertures, and they are astigmatism free for oblique-incidence light beams. A simple PML model is proposed for designing the quasi-toric PML. Fabricated quasi-toric PML's were evaluated to demonstrate their chip-to-chip interconnection probability.
