Abstract
Provided is an optical isolator that can reduce scattering of reflected return light in the interior of the housing and thus has excellent reliability. An optical isolator 1 includes: a first polarizer 2 provided on a light incidence side in a direction X of an optical axis; a second polarizer 3 provided on a light exit side in the direction X of the optical axis; a Faraday rotator 4 disposed between the first polarizer 2 and the second polarizer 3; and a housing 6 containing the first polarizer 2, the second polarizer 3, and the Faraday rotator 4, wherein the first polarizer 2 is configured that reflected return light A having transmitted the second polarizer 3 and the Faraday rotator 4 is reflected in a different direction from the direction X of the optical axis, and an absorbing member 5 that absorbs at least part of the reflected return light A is provided with an absorbing member 5 that absorbs at least part of the reflected return light A in an optical path of the reflected return light A having reflected in the different direction from the direction X of the optical axis.
