摘要： In an optical switch, fibers in a fiber array are arranged in a row. When a region where lights input into or output from the fibers in the fiber array intersect is taken as an intersecting position C, and an axis parallel to the fibers in the fiber array and passing through the intersecting position C is taken as a Z axis, then a distance δ between a core of a desired fiber among the fibers and an optical axis of a corresponding one of the lenses varies depending on a distance S of the desired fiber from the Z axis.

A laser beam emitted by the semiconductor laser impinging upon the glass prims is reflected by the dielectric film and is projected onto the record medium by the objective lens. A return beam reflected by the record medium is incident upon the dielectric film via the objective lens, and a part of the return beam transmitted through the dielectric film is separated by the birefringent prism into a first ordinary beam and a second extraordinary beam which are received by the first and second photodectors, respectively. The glass prism and birefringent prism are made of materials which satisfy a condition that a difference between refractive indices of the birefringent prism for ordinary light and extraordinary light is not less than 0.03 and a difference between a refractive index of the glass prism and at least one of the refractive indices of the birefringent prism is not less than 0.15.
