Abstract
A polarization-dependent type directional isolator. The polarization-dependent type directional isolator comprises a pair of first optical means positioned at a path along which light travels for changing the rotation direction of an incident light depending on the traveling direction of the incident light; a pair of second optical means for rotating the incident light by a given angle; and a third optical means positioned between the pair of second optical means for passing through only specific components of the components of the incident light, thereby making it possible to obtain laser outputs oscillating in both directions independently.
