Supermat Intl. develops three-dimensionally (3D) coherently ordered nano-gels and nano-composites of conjugated polymers, which are characterized by slow light propagation and highest stability under laser irradiation, and can be used for elaboration optical amplifiers and components for telecommunication.

The speed of the light in vacuum is extremely fast (C = 10x8 m s-1). I material systems, characterized by the frequently-dependent index of refraction n (v), the phase velocity Vp is defined as Vp = C / n(v). In material with a refractive index that is frequency-dependent, each frequencies of pulse of light propagate with a different phase velocity, thereby that the pulse temporarily shifted. This speed is known as the group velocity Vg. The group velocity differs from the phase velocity of light be the term that depends on the dispersion of the refractive index dn/dv. Vicinity of the optical resonance dispersion mechanism can lead to large slow-light effects. However, the optical pulse bandwidth in this case has to be limited to the spectral region over the which there is essentially a linear variation of n(v).

Currently, there are two fundamental directions to transfer the slow light effects to practice. One uses a material dispersion and the other structural dispersion. The first one based on opto-electronic effects which lead to rapid frequency variation of the refractive index such as electromagnetically induced transparency or stimulated Raman scattering. And the second on dispersion characteristics of two-dimensionally or three dimensionally ordered nano-materials with multi-dimensional periodicity, which are referred to as photonic crystals.

These phenomena find application as photonic bandgap materials, nanolasers, photonic integrated circuits, optical amplifiers and telecommunication components.

A key issue of wide application of slow light effects in telecommunication is a highest (optical quality) structural order in 3D material and a wide modulation bandwidth.

We elaborate new generation of 3D photonic crystals 3D coherently ordered nano-gels and nano-composites of conjugated polymers in matrices of saturated polymers. They characterized by high structural order, transparency window in near infrared region and possess simultaneously material and structural dispersion at laser beam (pulse) propagation.

3D coherently ordered composites of conjugated polymers can be used in telecommunication for elaboration of:

- optical amplifiers;
- optical gates;
- optical modulators;
- optical components.

High intensity Raman labels and standards will become commercially available in Jan 2008.

We are looking for funds and strategic partners to further along our development.

Supermat Intl. will shortly relocate from NY depending on the needs of the business.
