ABSTRACT:
Described are various optical, opto-electrical and electrical components and subsystems. Some embodiments include input and output waveguides supporting opposing facets separated by a gap. The degree to which the opposing facets are aligned with respect to one another controls the light intensity in the output waveguide. An active closed-loop control mechanism dynamically controls the extent of waveguide alignment to maintain a desired output intensity. In other embodiments, the path between opposing facets can be selectively blocked by a micro blade. Still other embodiments combine switching with optical power equalization for ease of integration.
