Abstract
In this work, a reconfigurable 1 × 2 optical router has been designed and experimentally tested. The router allows blocking or redirecting the input light beam to only one of the output ports or to the two output ports simultaneously. A control of the optical power level at each output has also been carried out. As the optical input power fluctuates, the output power is monitored and a feedback control loop adjusts the attenuation and maintains the output power level at a relatively constant level.
