TL;DR: In this paper, the most recent progress in this field is reviewed, covering the integration approaches of III-V-to-silicon bonding, transfer printing, epitaxial growth and the use of colloidal quantum dots.

TL;DR: In this paper, the authors review the work on heterogeneous III-V-on-silicon photonic components and circuits for applications in optical communication and sensing and elaborate on the integration strategy and describe a broad range of devices realized on this platform.

TL;DR: In this paper, a silicon-based photonic integrated circuit technology for applications beyond the telecommunication wavelength range is discussed, where the strong nonlinearity of silicon combined with the low nonlinear absorption in the mid-infrared is exploited to generate picosecond pulse based supercontinuum sources, optical parametric oscillators and wavelength translators connecting the tele communication wavelength range and the midinfrared.

TL;DR: A compact 2 μm wavelength widely tunable external cavity laser using a silicon photonic IC for the wavelength selective feedback is shown and an on-chip photothermal transducer using a suspended silicon-on-insulator microring resonator used for mid-infrared photothermal spectroscopy is shown.

TL;DR: The interface dominated high UV photocatalytic activity and degraded photoluminescence strength of composite catalyst confirmed the heterostructure effect between Ag( 2)O nanoparticles and TiO(2) nanobelts.
