Beschreibung
Zusammenfassung:A voltage controlled optical directional coupler (VCODC) having a coupling ratio that can be adjusted to any desired value through voltage tuning is disclosed. The VCODC may include a first optical hybrid coupler and a second optical hybrid coupler, which may be coupled with each other via one or more voltage controlled optical elements having a variable transparency depending on a voltage applied to the one or more voltage controlled optical elements. The VCODC may be configured to divert a portion of optical power received to a trunk input of the VCODC to a tap output of the VCODC based on the variable coupling ratio of the VCODC, which may be dependent on the variable transparency of the one or more voltage controlled optical elements.
