Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 15:
16. The polarization decomposition device of claim 14,
a second phase shifter configured to delay a phase of the first polarized light or the second polarized light;
a second polarization rotator configured to rotate the first polarized light or the second polarized light so that the polarization direction of the first polarized light or the second polarized light is changed; and
an second interference beam splitter configured to split the first polarized light and the second polarized light in which the phase is delayed, the polarization direction is rotated, or both, into a fifth polarized light and a sixth polarized light, split the optical signal having a fifth polarization direction which is different from at least part of the first and second polarization directions into the fifth polarized light, and split the optical signal having a sixth polarization direction different from the fifth polarization direction into the fourth polarized light.
