Abstract
An optical isolator core includes: a first birefringent crystal, a Faraday rotator, a second birefringent crystal, and a third birefringent crystal that are successively arranged along a forward optical path. In response to forward o light and forward e light successively traveling through the aforementioned optical elements, displacements of exit points of the forward o light and the forward e light with respect to an incident point are the same, and the forward o light and the forward e light are merged as exiting forward light. In response to backward o light and backward e light successively reversely traveling through the aforementioned optical element, displacements of exit points of the backward o light and the backward e light with respect to the incident point of the forward light causes the backward o light and the backward e light to deviate from the forward optical path.
