High-performance surface grating couplers for fiber-chip and free-space coupling
Sánchez-Postigo, Alejandro; Barona-Ruiz, Miguel; Ginel-Moreno, Pablo; Schmid, Jens H.; Ortega-Moñux, Alejandro
; Wangüemert-Pérez, J. Gonzalo; Luque-González, José Manuel; Halir, Robert; Cheben, Pavel; Molina-Fernández, Íñigo[et al.] (2025)
Surface grating couplers are key components in silicon photonics, as they act as efficient fiber-chip and free-space optical interfaces. Here we review some of our latest advances in these devices, including fiber-chip ... -
Suspended silicon waveguides for long-wave infrared wavelengths
Soler Penadés, Jordi; Sánchez-Postigo, Alejandro; Nedeljkovic, Milos; Ortega-Moñux, Alejandro; Wangüemert-Pérez, J. Gonzalo; Xu, Yolanda; Halir, Robert; Qu, Zhibo; Khokhar, Ali Z.; Osman, Ahmed; Cao, Wei; Littlejohns, Callum G.; Cheben, Pavel; Molina-Fernández, Íñigo; Mashanovich, Goran Z.[et al.] (Optica Publishing Group, 2018-02-09)
In this Letter, we report suspended silicon waveguides operating at a wavelength of 7.67 μm with a propagation loss of 3.1±0.3 dB/cm. To our knowledge, this is the first demonstration of low-loss silicon waveguides at such ...
