Silicon has long been established as the material of choice for the microelectronics industry.
This is not yet true in photonics, where the limited degrees of freedom in material design …

Erbium‐doped fiber devices have been extraordinarily successful due to their broad optical
gain around 1.5–1.6 µm. Er‐doped fiber amplifiers enable efficient, stable amplification of …

Transfer of energy occurs endlessly in our universe by means of radiation. Compared to
energy transfer (ET) in free space, in solid state materials the transfer of energy occurs in a …

Silicon photonics is no longer an emerging field of research and technology but a present
reality with commercial products available on the market, where low‐dimensional silicon …

Nanocrystals (NCs), representing a zero-dimensional system, are an ideal platform for
exploring quantum phenomena on the nanoscale, and are expected to play a major role in …

Ratiometric near‐infrared (NIR) fluorescence holds great promise for important applications
such as temperature sensing, food safety detection, and biological imaging owing to its self …
