Block-Based Mode Decomposition in Few-Mode Fibers
PhotonicsA block-based mode decomposition (BMD) algorithm is proposed in this paper, which reduces computational complexity and enhances noise resistance. The BMD uses randomly selected sample blocks of the beam images to restore mode coefficients instead of all ...

Interconnection of Few-Mode Fibers and Photonic Integrated Circuits Using Mode-Field Adapters
Photonics, 2022 We propose a detailed method for the interconnection between optical fibers and waveguides of photonic integrated circuits. Appropriate modal transmission is accomplished by matching the mode field diameters from both waveguide structures. Links from one
