Message

We are studing about organic materials such as the liquid crystals and the polymers
to apply them into opto-electronics techinologies.
Espetially, we fabricate diffraction gratings which can control not only propagation direction
but also polarization state of incident polarized light waves by using photo-crosslinkable
polymer liquid crystals and molucular alignment techniques.
These devices would be applicable to
