Abstract :
A metamaterial rectangular tap design is introduced and numerically simulated. The tap proves its efficiency in improving light tapping compared to taps composed of positive-index materials. The tapped beam is narrow for efficient collimation. In addition, the tapped light power can be easily controlled by adjusting the tap length and depth inside the waveguide. From the simulation, the peak of the tapped power from the metamaterial tap (n=-1) is about 32.2% of the guided power while the tapped power from the positive-index material tap with identical dimensions and n=1.51 is only 4.4%. This means that the metamaterial tap do not need to be fabricated deeply in the waveguide for reasonable tapped power.
