Discoveries and inventions periodically cause new technological
developments within human societies. Key inventions and their
accompanying economic and social changes can be seen as the main
promoters of technological and structural progress. Many examples
of change can be traced back to key inventions. At the end of the
last century, one of the major lines of technological development
was the implementation of electricity, the introduction of electric
current. Inno vations were generated both by applying the "low
quality" thermal and energy transmission properties, as well as by
studying "high quality" characteristics like signal processing and
electromagnetic wave propagation. In the field of signal
processing, particular devices like the thermionic valve, the
transistor and the (micro) chip deserve mention. Regarding energy
generation, distribution and consumption, huge investments were
made in coal and nuclear power plants, as well as in consumer and
industrial electric appliances. Which innovations can be expected
to improve or replace some of the applications (products,
processes) of electricity? Thinking of an important technology
invented about three decades ago - the laser - coherent light plays
the key role in the process ("light amplification by stimulated
emission of radiation"). Thus the new term technologies of light
can be used for such innovations. Extending the definition,
"technologies of light" or "photonics" can be defined as any
methods, processes or products which make use of the spectrum of
light, and any systems whose function is to study, measure,
transform or transmit by means of light."
