Optical gate controlled by temperature.

Meshkovsky I.K., Fuad M.A, Alyev F.M., Baushev V.N.

Vol. 30, nr 4

581-583

Light scattering and transmission of a porous silicate glass-based composition material with poly-2-ethylhexylactylate immobilized in the pores have been investigated. A temperature transition (47-50 degrees C) in transmittance has been observed and interpreted. The hysteresis found indicates that the second order transition occurs.

High radiation durability of optical elements made of porous glass.

Optical properties of elements made of silicate porous glass are measured after their exposure to gamma -radiation. Extraordinary radiation durability of porous glass has been found and interpreted.

Formation of microoptical elements in the bulk of composition material on the basis of porous glass.

The possibilities of the formation of microoptical elements in the bulk of composite material on the basis of porous glass have been investigated. It has been demonstrated that due to the local laser heating-up of composition material, the local desorption of the adsorbate from a porous matrix is initiated that causes formation of microlenses. Other possibilities of microoptical filters formation have been studied based on electrodiffusion immobilization of dye ions. Characteristics of such elements are studied and possible applications are discussed.
