Abstract
This article focuses on electro-optical modulators and in particularly it concerns a high efficiency modulator based on a multi-taper coupler. The advantages achieved by adding a modulator located on the multi-taper are: increasing the efficiency, bandwidth, versatility and decreasing the propagation loss while decreasing the connection gate and the location on the PIC, all due to the Multi-Taper coupling sensitivity. Numerical simulations will show the feasibility of changing the coupling efficiency dramatically by a small change on the multi-taper coupler, where coupling efficiency changes dramatically, from 3dB loss up to 38dB loss. The fabrication process will be shown for manufacturing the multi-taper modulator.
