Foreword
Semiconductor photonics have for long delivered key platforms to enhance technologies we use in our daily lives. Nowadays, more and more functionalities and improvements rely on nanomaterials and quantum structures, which experts all around the
world study and develop for numerous applications.
When I first met the author of this book, Arash, in the year of 2014 during his
visit to the Zhejiang University, I was impressed by his work on the demonstration of
electrically-driven polariton laser, which became a prominent topic of our scientific
encounter. Soon after that, our friendship was not only established because we shared
a similar background on cavity quantum electrodynamics, but also due to his broad
scholarly interests as well as benign and sincere character.
Our academic partnership was established during his next visit in one of the
following years, starting with a joint undergraduate course, Semiconductor quantum
structures for photonic devices, at the Zhejiang University. This course turned out
to be a very successful one, highly rated by all the students in the class; and closely
related to the subject of this book, it turns out years later. It was hence repeated
and exchange students from both sides were a further step, which resulted in fruitful
accomplishments.
One major topic, which this book addresses right from the beginning, is the content
of a Sino-German Symposium which took place in 2018 in Hangzhou. During
this memorable event, I fortunately could assist Arash and co-host Huizhen Wu
in the superb organization of the first Functional Nano-Materials Sciences Symposium at the Zhejiang University, and then even was invited to partner in a SinoGerman Cooperation Group on functional nano-materials sciences research which
they successfully established shortly after.
Though the outbreak of COVID-19 has impeded international collaborations and
travel since last year, our distance actually is shortened by the internet while I, together
with several graduate students from Zhejiang University, are enjoying Marburg’s
web-based course Quantum technology taught by Arash at the Philipps-Universität
Marburg this winter; a small remedy for not having the joint course in Hangzhou this
year. I see that some of the relevant topics are also summarized in this book.
