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 ... -
Millimeter-long metamaterial surface-emitting antenna in the silicon photonics platform
Ginel-Moreno, Pablo; Sánchez-Postigo, Alejandro; De-Oliva-Rubio, José; Hadij-ElHouati, Abdelfettah; Ye, Winnie N.; Wanguemert-Pérez, Juan Gonzalo; Molina-Fernández, Íñigo; Schmid, Jens H.; Cheben, Pavel; Ortega-Moñux, Alejandro[et al.] (Optical Publishing Group, 2021-07-28)
Integrated optical antennas are key components for on-chip light detection and ranging technology (LIDAR). In order to achieve a highly collimated far field with reduced beam divergence, antenna lengths on the order of ...
