Modeling of semiconductor optical amplifiers

Mørk, Jesper; Bischoff, Svend; Berg, Tommy Winther; Nielsen, Mads Lønstrup; Öhman, Filip

We discuss the modelling of semiconductor optical amplifiers with emphasis on their high-speed properties. Applications in linear amplification as well as ultrafast optical signal processing are reviewed. Finally, the possible role of quantum-dot based optical amplifiers is discussed.

The Dynamics of Semiconductor Optical Amplifiers – Modeling and Applications

Mørk, Jesper; Nielsen, Mads Lønstrup; Berg, Tommy Winther

Optics and Photonics News — 2003, Volume 14, Issue 7, pp. 42-48

The importance of semiconductor optical amplifiers is discussed. A semiconductor optical amplifier (SOA) is a semiconductor laser with anti-reflection coated facets that amplifies an injected light signal by means of stimulated emission. SOAs have a number of unique properties that open up

A second order model of noise in saturated semiconductor optical amplifiers

Öhman, Filip; Tromborg, Bjarne; Mørk, Jesper

Cleo/europe-eqec 2005 Conference Digest Cd — 2005, pp. 10

We have developed a second order model of spontaneous emission noise in semiconductor optical amplifiers (SOAs). The resulting noise distributions agree well with statistical simulations and explain the measured redistribution of noise in saturated SOAs.

Semi-analytical model of filtering effects in microwave phase shifters based on semiconductor optical amplifiers

Chen, Yaohui; Xue, Weiqi; Öhman, Filip; Mørk, Jesper

Semi-analytical Model of Filtering Effects in Microwave Phase Shifters Based on Semiconductor Optical Amplifiers — 2008

We present a model to interpret enhanced microwave phase shifts based on filter assisted slow and fast light effects in semiconductor optical amplifiers. The model also demonstrates the spectral phase impact of input optical signals.
