Stirling, Callum J.; Halir, Robert
; Sánchez-Postigo, Alejandro; Qu, Zhibo; Reynolds, Jamie D.; Soler Penadés, Jordi; Murugan, Ganapathy Senthil; Ortega-Moñux, Alejandro; Wanguemert-Pérez, Juan Gonzalo; Molina-Fernández, Íñigo; Mashanovich, Goran Z.; Nedeljkovic, Milos[et al.] (Optical Publishing Group, 2021-10-19)
Beam splitters are core components of photonic integrated circuits and are often implemented with multimode interference couplers. While these devices offer high performance, their operational bandwidth is still restrictive ... -
Design of a suspended germanium micro-antenna for efficient fiber-chip coupling in the long-wavelength mid-infrared range
Sánchez-Postigo, Alejandro; Ortega-Moñux, Alejandro; Pereira-Martín, Daniel; Molina-Fernández, Íñigo; Halir, Robert; Cheben, Pavel; Soler Penadés, Jordi; Nedeljkovic, Milos; Mashanovich, Goran Z.; Wanguemert-Pérez, Juan Gonzalo[et al.] (Optica Publishing Group, 2019-08-05)
Recent developments of photonic integrated circuits for the mid-infrared band has opened up a new field of attractive applications for group IV photonics. Grating couplers, formed as diffractive structures on the chip ... -
Mid-infrared suspended waveguide platform and building blocks
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 germanium waveguides with subwavelength-grating metamaterial cladding for the mid-infrared band
Sánchez-Postigo, Alejandro; Ortega-Moñux, Alejandro; Soler Penadés, Jordi; Osman, Ahmed; Nedeljkovic, Milos; Qu, Zhibo; Wu, Yangbo; Molina-Fernández, Íñigo; Cheben, Pavel; Mashanovich, Goran Z.; Wanguemert-Pérez, Juan Gonzalo[et al.] (Optica Publishing Group, 2021-05-24)
In recent years, sensing and communication applications have fueled important developments of group-IV photonics in the mid-infrared band. In the long-wave range, most platforms are based on germanium, which is transparent ... -
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 ...
