Broadband and low-loss TM-pass polarizer using tilted subwavelength structures
Barona-Ruiz, Miguel; Pérez-Armenta, Carlos; Ortega-Moñux, Alejandro; Wanguemert-Pérez, Juan Gonzalo; Molina-Fernández, Íñigo; Cheben, Pavel; Halir, Robert[et al.] (Optica Publishing Group, 2022-10-10)Photonic systems built on the Silicon-on-Insulator platform exhibit a strong birefringence, and must thus be operated with a single polarization for most applications. Hence, on-chip polarizers that can effectively suppress ... -
