The microlens has a high numerical aperture (NA), of 0.9, in air with only one aspherical surface, and is 10–20 times smaller in diameter than a typical gradient refractive index (GRIN) microlens. The designs of aspherical microlenses with NAs of 0.3, 0.6, and 0.9 in air are aberration-free at three wavelengths (561, 590, and 630 nm). The full width at half maximum of the effective intensity point spread function of a …

To couple the elliptical mode field light beam of a laser radiation source to a circularly symmetric single-mode optical fiber, the end of the fiber is provided with an anamorphic lens. The double wedge-shaped lens provides high coupling efficiency and is easily constructed. Other anamorphic lenses are also disclosed. A single wedge lens can provide high coupling efficiency if it is formed on
