Description and expertise of the organisation:
ITME is the leading Polish government research and development centre:
- conducting scientific studies and development work in material engineering, solid state physics and electronics
- developing micro and nano technologies and materials
- designing and developing semiconductor devices such as: SiC and GaN diodes and transistors, lasers, photodetectors and passive components.
- developing characterisation methodes for materials structures and devices.

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.
