DESIGN AND MANUFACTURING OF A OPTICAL MULTIMODE INTERFERENCE DEVICES BASED ON A SILICON PHOTOTONIC INTEGRATED CIRCUIT

Abstract

In the near future, photonic chips will gradually replace electronic chips in a number of specialized fields due to their advantages, including broadband, high speed, and compatibility with current electronic chip manufacturing technologies. Researching and selecting typical basic components to build photonic chips is extremely important. The multimode interference component based on silicon material is is undergoing a thorough investigation and standardization process in order to be added to the industrial production library. In this paper, we propose a new property of the multimode interferer MMI 4x4, which simultaneously transmits two signals in the same phase or opposite phase at the inputs to perform switching in the same direction or opposite direction at the output on the same silicon photonic integrated circuit. This result will extend to the development of optical signal switchers, routers, splitters, or couplers for more complex functional circuits. We have achieved similar results between theoretical calculation, simulation, and actual manufacturing
