Research Highlights Student projects Optoelectronics
The research in optoelectronics mainly focuses on optical design and characterization of optical systems. Different systems have been developed such as: integrated optical sensors, wide field of view optical receiver for OWC systems and fiber based optical devices.
| Numerical modeling of integrated optical systems and nano-structures:
Waveguides/nano-wires
Mode properties
Device sensitivity to the changes of the surrounding refractive index
optoResearch1
Integrated surface plasmon resonance
Surface plasmon modes in thin film of gold caoted on nano-wire structure
Sensitivity of the plasmon mode to the changes of the surrounding index
optoResearch3
ZnO nano-rod structure
Guidance properties of the nano-rod
Scatterig phase function of the rod
Sensitivity of the rod (guidance/scattering) to the changes of the surrounding index | | The scattering properties of ZnO nano-rods grown on flat substrates are investigated using in house built nephlometers. Scattering properties help optimizing the growht of the rods for maximum light coupling into optical fiber when the rods are grown on them. | | Characterization of integrated optical systems including: waveguides, nano-wires fiber devices. Optical properties investigated are transmission, reflection and attentuation. Controlling those parameters can be used in applications such as sensing. |
