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 …

The field of optically pumped planar waveguide lasers has seen a rapid development over
the last two decades driven by the requirements of a range of applications. This sustained …

Three different broadband sensitization concepts for optically active erbium ions are
reviewed: 1) silicon nanocrystals, with absorption over the full visible spectrum, efficiently …

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 …

Silicon, the material par excellence for electronics, is not used for light sources because of
the lack of efficient light emitters and lasers. In this review, I will discuss the physical reasons …

Currently, electrical interconnections based on metal lines represent the most important
limitation on the performances of silicon-based microelectronic devices. The parasitic …

Light-emitting Si-rich silicon nitride (SRN) films were fabricated by plasma enhanced
chemical vapor deposition followed by low temperature (500–900 C) annealing. The optical …

Sensitization of Er emission by Si nanoclusters (Si-nc) is investigated with pulsed and
continuous optical pum**, in and off resonance with excited states of Er 3+ ion. We show …

The book gives an in-depth description of key devices of current and next generation fibre
optic communication networks. Devices treated include semiconductor lasers, optical …
