| 1 | Polarization-independent multimode interference coupler with anisotropy-engineered bricked metamaterial显示文摘Many applications, including optical multiplexing, switching, and detection, call for low-cost and broadband photonic devices with polarization-independent operation. While the silicon-on-insulator platform is well positioned to fulfill most of these requirements, its strong birefringence hinders the development of polarizationagnostic devices. Here we leverage the recently proposed bricked metamaterial topology to design, for the first time, to our knowledge, a polarization-independent 2 × 2 multimode interference coupler using standard 220 nm silicon thickness. Our device can be fabricated with a single etch step and is optimized for the O-band,covering a wavelength range of 160 nm with excess loss, polarization-dependent loss, and imbalance below 1 dB and phase errors of less than 5°, as demonstrated with full three-dimensional finite-difference time-domain simulations. | Carlos Perez-Armenta Alejandro Ortega-Monux Jose Manuel Luque-Gonzalez Robert Halir Pedro J.Reyes-Iglesias Jens Schmid Pavel Cheben Inigo Molina-Fernandez J.Gonzalo Wanguemert-Perez | 2022 | Photonics Research2022，10，4： | 2 |
