A novel approach to design photonic crystal based optical power splitter with a flow control mechanism

We proposed and demonstrated an efficient method to split electromagnetic wave in two dimensional photonic crystal by using a T-shaped splitter. By measuring normalized electromagnetic field, it is shown that the equal outputs of splitter can be limited and controlled by using a control rod which position can be varied. It is also showed that the output of two ports can be unequal and it can be controlled by varying the position of control rod.
