Product-sum photonic integrated circuit based on microring resonators and MMI coupler on SOI
Ruikang Luo, Kiyoto Takahata · 2021
A product-sum photonic integrated circuit consisting of SOI-based cascaded microring modulators and a 4×1 multimode interference coupler is proposed for CNN computing. A basic product-sum operation is numerically demonstrated for 2×2 matrix.
