Enter the world of photonium!

Under the Standard Model the photon is classified as an elementary spin-1 massless particle. On the contrary, the optical scientists are convinced that the photon can carry an orbital angular momentum - there is even a talk of half-integer angular momentum.

The mystery of the photon goes further in the conerefringent optics. The basic part of the CR optics is a conerefringent element, CRE.

When the photon has passed through one CRE, new aspects of its nature are revealed. la Stern-Gerlach experiments demonstrate that the passed-through photon is identifiable not only by its spin and momentum, but by more observables. The results are consistent with the conception of Jordan - de Broglie for a composite photon, photonium.

3 CREs

CR optics releases an avalanche of ideas for experimenting in the quantum and nonlinear optics, interferometry and spectroscopy, astronomy and particle physics. High on the list are the wavelength measurements of CRE-filtered beams.

The experiments of laser generation with Nd3+ doped CRE display unusual resonator modes. The photons of generated beam carry stable and reproducible orbital angular momentum - more than thousand (in h-bar units) has been detected with one CRE in semiconfocal resonator.

The photon variables, and its boson/fermion states, are easy ruled by CRE. Furthermore, the optical activity of a CRE can be modulated by magnetic or electric field.

When the scalar beam has passed through n CREs it generates 2n concentric rings. Photo: He-Ne non-polarized beam after 3 CREs. The well seen 4 rings exhibit fine splitting - Poggendorff dark ring.

CR optics carries the tools for a new generation photonic devices.

Our products are designed for the research labs in the photonics industry and academia. They also enable higher educational institutions to offer cutting-edge practical courses with topics from the CR optics.
