Mode-division multiplexing (MDM) is currently under study due to its potential to further increase data rates in optical communication circuits. In this paper, we propose an add/drop MDM for the first- and second-order modes that cover the whole C-Ba

We demonstrate a suspended germanium waveguide platform with a propagation loss of 5.3 dB/cm at a wavelength of 7.7 µm, with potential applications in free-space optical communications and absorption sensing. Furthermore, our simulations show low-lo

Subwavelength metamaterial structures in silicon waveguides open new degrees of freedom to control on-chip light propagation. They have been applied to many silicon photonic devices such as fiber-chip couplers, waveguide crossings, microspectrometers

We design perfectly vertical grating couplers with minimum feature sizes above 100 nm, high coupling efficiencies up to 75%, and low back reflection of -20 dB over 100 nm bandwidth, using a machine learning method.

Silicon-on-insulator (SOI) is the dominant platform in near-infrared silicon photonics. However, the high absorption of SiO2 at wavelengths above 4 μm limits the range at which this material can be used in the midinfrared wavelengths (2 – 20 μm).

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 the potential applications
