With the advancement of nanoscale semiconductor technology,semiconductor optical amplifiers are used to amplify and process all-optical signals. Inthis paper, with the aim of calculating the gain of quantum dot semiconductor opticalamplifier (QD-SOA), two groups of rate equations and the optical signal propagatingequation are used in the active layer of the device. For t...

Semiconductor technology has reached an end in the manufacture of conventional Metal Oxide semiconductor Field Effect Transistor (MOSFET). The continuous scaling of semiconductor devices has kept pace with Moore’s law and transistors below 1μm are grouped under deep sub-micron (DSM) technology node. But this trend seem to end beyond deep sub micron levels due to main design constraints such as ...

SUMMARY Today, practical semiconductor products are an integral part of our lives and the infrastructure of society, and this trend will continue in the future. New areas of application will expand into medical, environmental, and agriculture (food)-related fields in addition to the conventional information and communication technology (ICT)-related field. Low-cost semiconductor devices with ad...
