Semester Electives
Subject Code AVM870
Subject Title Photonic Integrated Circuits


Photonic Integrated Circuits (PIC) are highly promising to handle the quickly growing
data traffic in the near future where pure copper based electronic will fail to satisfy
the requirements of bandwidth and distance. This course deals with principles,
devices and applications that enable the integration of various photonic devices and
circuits on a single chip.
