Abstract
An optical isolator coupled to a thermally expanded multiple core fiber. The thermally expanded multiple core fiber having at least one input core and one output core. The optical isolator to propagate light from an input core to an output core, while inhibiting the propagation of light from an output core to an input core of the thermally expanded multiple core fiber. The fiber cores having expanded mode field diameters that may facilitate coupling to the optical isolator and reduce component size in the optical isolator.
Claims20
An optical isolator, comprising:
- a thermally expanded multiple core fiber having at least one input core and at least one output core;
- and
- an isolator core coupled to the thermally expanded multiple core fiber to propagate light from the at least one input core to the at least one output core and inhibit the propagation of light from the at least one output core to the at least one input core.
An optical isolator, comprising:
- a thermally expanded multiple core fiber having at least one input core and at least one output core;
- and
- a first isolator core and second isolator core coupled to the thermally expanded multiple core fiber to propagate light from the at least one input core to the at least one output core and inhibit the propagation of light from the at least one output core to the at least one input core.
