device for continuous adoption of a coherent and linearly polarized light source.

摘要

Device making it possible to continuously tune a coherent, linearly polarised light source. …??It comprises an electro-optical means (5) forming a spectral filter having an electrically modifiable transfer function, this electro-optical means being provided in order to select a particular longitudinal mode from the set of longitudinal modes able to oscillate inside the outer cavity with which the source (1) is equipped, and which is terminated by a means (3) of reflecting, towards the source, the light emitted by this source, and an electro-optical means (4) of variation of the optical length of the cavity, this means of variation being placed in the cavity and provided in order to continuously displace the position of the longitudinal mode selected, each electro-optical means comprising a solid electro-optical crystal. …??Application to optical telecommunications. …IMAGE…
