Integrated optical component combine the functions of a Variable Optical Attenuator (VOA), a tap coupler, and a photo-detector, reducing the size, cost, and complexity of these functions. In other embodiments, the integrated optical component combines the functions of an optical switch, a tap coupler, and a photo-detector. A rotatable mirror is used to adjust the coupling of light from an input port or ports to one or more output ports. A pin hole with a surrounding reflective surface is used at the core end face of one or more output fibers, such that a portion of the output optical signal is reflected to a photodiode chip. The photo-detector provides an indication of the optical power that is being coupled to the output fiber. With appropriate electronic control circuitry, the integrated optical component can be used to set the output optical power at a desired or required level.
