Abstract
The embodiments of the present disclosure discloses an optical isolator core and an optical isolator. The optical isolator core comprises: a first birefringent crystal, a first Faraday rotator, a second birefringent crystal, a second Faraday rotator, and a third birefringent crystal that are successively arrange in the forward light path, all of which are parallel plate structures. The embodiments of the present disclosure achieves backward isolation for polarization-independent and non-collimating beam which simplifies the device structure and assembly process, thereby reduce size and cost.
