Abstract
For regenerating a binary optical signal (sd, sE2) a monolithic semiconductor component (100) comprises: a saturable absorber structure (3) having a saturable absorber section (31), a first optical waveguide (1, 11 to 16) defining a first guide axis (X) disposed on either side of the section (31), a second optical waveguide (2, 21 to 24) defining a second guide axis (Y) crossing the first axis (X) in the section (31) and disposed on either side of the section (31). The saturable absorber structure has a dimension along the first guide axis greater than its dimension along the second guide axis. The first and second waveguides respectively inject an optical clock signal (c1) and the binary optical signal (sd, sE2). Application to optical transmission systems for regenerating signals in accordance with two different regeneration regimes.
