Research and resources pageSilicon based Hi Q micro/nano cavities and devices
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 micro/nano
Hi-Q cavity resonators like microring structures and photonic crystals in
silicon. Specific Research work : - Realizing novel microring architectures like MRDC, Doublet Ladder filters etc. - Realizing extremely compact microrings - Microring filter synthesis procedure for spectral engineering applications. - Investigating the above synthesis procedure for Photonic cystals - Plane wave method and FDTD based investigation of photonic bandgaps in silicon - Fabrication of the above mentioned devices on a Silicon-On-Insulator (SOI) wafer. Facilities and Tools used: - Nanophotonics Research Lab (ECERF W4-087) is equipped with nano-positioning stages and instrumentation for characterizing and performing experiments with nano-electrooptic devices. -
In house FDTD and PWE codes for simulations
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. |
