A monomode optical fiber, and a process for manufacturing such a fiber, that comprises a monomode core and at least one cladding encircling the core. The monomode core comprises at least two zones, a first zone with at least one first refractive index and a second zone with at least one second refractive index different from the first refractive index. The difference between the first refractive index and the second refractive index is of the same order of magnitude as the variation in the refractive index of the second zone between the inactive state and the active state of the fiber.

A device for the excitation of a gas medium () contained in a casing (), the device being coupled to the casing () and disposed outside same and including an applicator that can generate lateral excitation inside the casing () over at least a portion thereof. The device is characterized in that the casing () is a hollow-core photonic dielectric structure (), in which the core has a diameter smaller than 300 &#x3bc;m, and in that the applicator is of the microwave type and can be used to generate a surface wave that can create and confine a microplasma from the gaseous medium contained in the casing ().
