摘要：A variable splitting optical coupler includes a first port assembly, a second port

assembly, a movable deflecting element assembly and a third port assembly. The first

port assembly includes a first lensing element and receives a first optical signal. The

second port assembly includes a second lensing element and emits a variable

transmitted portion of the first optical signal. The movable deflecting element assembly

includes a movable deflecting element positioned between the first and second port

assemblies. The third port assembly includes a third leasing element. The movable

deflecting element is so positionable and the third port assembly is so positioned and

arranged so that a deflected portion of the first optical signal is deflected from the

deflecting element and directed through the third port assembly. The variable

transmitted portion of the first optical signal is directed through the second port

assembly without being deflected by the deflecting element. The transmitted and

deflected portions of the first optical signal are expanded and collimated, while passing

through the optical coupler by appropriate positioning of the lensing elements to

provide efficient and accurate control of the first optical signal. The movable deflecting

element varies the relative splitting of the deflective and transmitted portions of the first

optical signal.
