Research interests / Project ideas
Active and passive components for FTTH access network, such as:
- Supercontinuum light sources based on microstructured optical fibres for DWDM.
- Nanostructured optical fibres for line dispersion compensation.
- PBG fibres for HDWDM delivery in FTTH.
- Apodised FBG gratings with superior side lobe compression for fibre fault monitoring in FTTH.
- Materials with the refractive index depending upon the elecric field based on MQW.
