Sánchez-Postigo, Alejandro; Wanguemert-Pérez, Juan Gonzalo
; Soler Penadés, Jordi; Ortega-Moñux, Alejandro; Nedeljkovic, Milos; Halir, Robert; El Mokhtari Mimum, Faysal; Xu Cheng, Yolanda; Qu, Zhibo; Khokahr, Ali Z.; Osman, Ahmed; Cao, Wei; Littlejohns, Callum G.; Cheben, Pavel; Mashanovich, Goran Z.; Molina-Fernández, Íñigo[et al.] (Wiley, 2019-04-01)
In this work, the authors present their recent progress in the development of a platform for the mid-infrared wavelength range, based on suspended silicon waveguides with subwavelength metamaterial cladding. The platform ... -
Suspended silicon integrated platform for the long-wavelength mid-infrared band
Sánchez-Postigo, Alejandro; Wanguemert-Pérez, Juan Gonzalo; Soler-Penades, Jordi; Ortega-Moñux, Alejandro; Nedeljkovic, Milos; Halir, Robert; El Mokhtari Mimun, Faysal; Qu, Zhibo; Khokhar, Ali Z.; Osman, Ahmed; Cao, Wei; Littlejohns, Callum G.; Mashanovich, Goran Z.; Cheben, Pavel; Molina-Fernández, Íñigo[et al.] (2019-07-18)
The atmospheric-transmission window and the fingerprint region of many substances overlaps with the long-wave infrared band. This has enabled the emergence of a new path for photonic integrated circuits, which could exploit ... -
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 ...
