摘要:
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).
