An electrooptic photonic crystal fiber having a central part forming a Bragg structure, the central part comprising a core (1) made homogeneously from low refractive glass and pre-designed set of altering claddings made of high refractive (2) and low refractive glasses (3); and a peripheral part forming an envelope of the Bragg structure, the peripheral part (5, 7) being formed from multicomponent glasses with low viscosity in the fiber drawing temperature range. Metallic electrodes (8) are embedded in the peripheral part adjacent to the central part on diametrically opposite sides. The method for manufacturing such a fiber includes drawing of separate rods from glass bars constituting fiber elements, drawing of electrodes in the form of metal filled glass capillaries, bundling a package with hexagonal section and internal Bragg structure from the rods, drawing a rod from the package, assembling a secondary package from the rods with Bragg structure, electrode capillaries and glass rods forming the envelope of Bragg structure, re-drawing the secondary package into a preform and then into photonic crystal electrooptic fiber.
