Abstract:
The invention concerns a spiral spring made from a photostructurable glass plate by UV irradiation, heat treatment and chemical etching, said glass having a thermal coefficient of Young modulus CTE 0 . By UV irradiation through one or more masks, optionally completed by a heat treatment, selected zones of the spiral spring have a CTE 0 modified into a CTE i value.

Abstract:
The present invention relates to a method of fabricating a resonator in a substrate, characterized in that it comprises the following steps: a) modifying the structure of at least one zone of the substrate so as to render said at least one zone more selective; b) etching said at least zone so as to selectively fabricate said resonator.
Abstract:
A stabilised gain semiconductor optical amplifier (CG-SOA) includes and active waveguide (1) comprising an amplification medium (2), extending in longitudinal (Z), lateral (X) and vertical (Y) directions, and coupled to a laser oscillation structure comprising at least two resonant cavities (13, 14) extending in first (D1) and second (D2) directions which are different from the longitudinal direction (Z) of the active waveguide (1) and arranged in such a way as to permit the establishment of laser oscillations having at least two different relaxation oscillation frequencies.
