摘要

The invention relates to devices permitting the shifting of the frequency of an optical wave. …??It consists in exciting two coupled light guides (422, 423) by an optical wave propagating in a symmetric mode and in subjecting these guides to the action of a travelling electromagnetic wave which has the effect of shifting the frequency of the optical wave which passes from the symmetric mode to the antisymmetric mode. A transfer device (432-435) supplied with a DC voltage V0 permits the retransformation of the antisymmetric mode into the symmetric mode in order to add the two light signals and to obtain a single translated output signal of the frequency F. …??The invention permits the construction of BLU optical modulators. …IMAGE…
