Abstract
A waveguide comprises an annular cross-section and a first numerical aperture (NA) at one end. The waveguide further comprises either an annular or circular cross-section at the other end, which has a second NA. The waveguide has a progressively-varying NA, which varies from the first NA (at one end) to the second NA (at the other end).
Claims12
An apparatus, comprising:
- a first end guiding light having a first numerical aperture (NA), the first end further having an annular cross-section;
- a second end guiding light having a second NA, the second end further having a circular cross-section;
- and
- a waveguide between the first end and the second end, the waveguide producing a varying NA that progressively transitions from the first NA to the second NA.
