We demonstrate compressive-sensing (CS) spectroscopy in a planar-waveguide Fourier- transform spectrometer (FTS) device. The spectrometer is implemented as an array of Mach …
Grating couplers enable position-friendly interfacing of silicon chips by optical fibers. The conventional coupler designs call upon comparatively complex architectures to afford …

A polarization beam splitter (PBS) is proposed and realized for silicon photonic integrated circuits with a 340-nm-thick silicon core layer by introducing an asymmetric directional …
The high index contrast of the silicon-on-insulator (SOI) platform allows the realization of ultra-compact photonic circuits. However, this high contrast hinders the implementation of …
Controlling the group velocity dispersion of silicon nanophotonic waveguides has been recognized as a key ingredient to enhance the development of various on-chip optical …
We present two techniques for mitigating the effects of temperature drifts in waveguide spatial heterodyne Fourier-transform on-chip spectrometers. In high-resolution devices …
Subwavelength grating (SWG) waveguides are integrated photonic structures with a pitch substantially smaller than wavelength for which they are designed, so that diffraction effects …

With the assistance of subwavelength grating (SWG), an ultra-compact multimode interference (MMI) based diplexer is proposed. A certain number of SWG pitches are …
We demonstrate two single-etched sub-wavelength grating coupler (SWGC) designs for O- band application, one targeting at high coupling efficiency and the other targeting at broad …
