Nanophotonics
is about guiding, confining, and
manipulating light at nanometer scale. A similar definition holds for
microphotonics devices at micron scale. My research work revolves
around exploring silicon based micro/nano photonic devices like
microring structures and photonic crystals etc. In particular i design,
fabricate and characterize microring based WDM filters in
Silicon-On-Insulator (SOI) material system

The aim of
this research project is to address the issues in
the transmission of RF signals like UWB or Wireless LAN signals over
cheaper Multimode Optical fiber links which are evolving along with the
Gigabit/10G Ethernet standards. These Multimode fiber links are based
on 850nm VCSEL laser diodes and Laser optimized Graded Index fibers and
is meant for short distances up to 300 to 550 meters for a 10GHz
bandwidth. This research would provide a low cost solution for the
extension of the coverage range for the wireless networks mentioned.
