The basic active element of the Internet are optical fibres using quantum well lasers.
My former boss (I have worked for myself for a long time now) was an
Australian quantum semiconductor device physicist and he was the one who
first did the experiment to observe the quantum well effect that then
in turn made the quantum well laser possible.
He was one of the smartest people I've ever known and he did these things
and other significant achievements well before I met him. Alas I am just
a humble engineer and by comparison I have no expertise or involvement in these areas.
The lasers are also used in every CD, DVD, Blu-Ray player and barcode reader ever made.
