Abstract
The optical coupler includes first, second and third port assemblies and a deflecting element. The first port assembly receives a first optical signal, the first port assembly including a first lensing element. The second port assembly emits a predetermined, transmitted portion of the first optical signal. The second port assembly includes a second lensing element. The deflecting element is positioned between the first and second port assemblies. The third port assembly includes a third lensing element. The deflecting element and the third port assembly are so positioned and arranged such that a deflected portion of the first optical signal is deflected from the deflecting element and directed through the third port assembly. The predetermined, 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.
