You see, wire telegraph is a kind
of a very, very long cat. You pull
his tail in New York and his head
is meowing in Los Angeles. Do
you understand this? And radio
operates exactly the same way:
you send signals here, they receive
them there. The only difference is
that there is no cat.
A. Einstein

Acknowledgments
I would like to acknowledge all the people who, in different
ways, supported me during my dissertation.
In the first place, I would like to thank my “Doktorvater” Prof.
Werner B¨achtold for giving me the opportunity to work in such
a valid research group. I would also like to express my gratitude
to Prof. Heinz J¨ackel and Prof. Massimo Vanzi who accepted
to be my coexaminers.
I would like to acknowledge Otte J. Homan for his (not only)
scientific support, Hanspeter Meier for his patient and indis-
pensableworkincircuitfabrication,andHansruediBenedickter
for revealing me the fine art of high-frequency characterization.
My gratitude goes also to Bruno Graf from Avalon Photonics
for helping us in the dielectric layer deposition, to Iwan Schny-
der, for bearing with me the “slings and arrows” of the project,
and to Dominique Schreurs for sharing her great experience in
device modeling.
A special thank goes to all my friends and colleagues at the in-
stitute, for the cheerful working atmosphere they managed to
create. Thanks to Franck Robin for convincing me to wake up
early to go skiing, climbing, or hiking, to Thomas Brauner for
his patience with my poor sailing skills, to Esteban “Abuelo”
Moreno for being always willing to try my latest brownies
recipe, and to Federico Beffa for showing me a delicious al-
ternative to the ETH Mensa.
Un ringraziamento speciale va anche ai miei genitori, per il loro
inesauribile sostegno, alla mia psicologa personale e a tutte
le persone che mi sono state vicine in questi anni passati a
“dissertare”.
