WebJan 5, 2024 · A WMC can function as a circulator or a combiner with much better isolation/directivity from ports 2 and 3 than a coupler. This three-port device allows light incident on port 1 to travel in only one direction (transfer), while allowing bi-directional travel between ports 2 and 3 (transmission). WebDirectivity describes the ratio of light emission in one particular direction to the total over all other directions. It is often useful for emitters to have high directivity so that all of the...
