Patent ID: 6954594

Claim:
A monolithic semiconductor component ( 100 ) for regenerating in accordance with different first and second regeneration regimes an optical data signal (s d , s E2 ) in the form of an optical carrier wave amplitude modulated at a modulation frequency, said regeneration using an optical clock signal (c 1 ) with a repetition frequency substantially equal to said modulation frequency, said component comprising: a saturable absorber structure ( 3 ) having at one end (Ex 1 ) a first saturable absorber section ( 31 ); a first optical waveguide ( 1 , 11 to 16 ) defining a first guide axis (X) disposed on either side of said first section and adapted to inject said clock signal (c 1 ) into said first section, an output (S 1 ) of said first waveguide ( 1 ) being adapted to deliver a first data signal (s 1 ) regenerated in accordance with said first regime; and a second optical waveguide ( 2 , 21 to 24 ) defining a second guide axis (Y) crossing the first axis (X) in said first section and disposed on either side of said first section ( 31 ), the second waveguide being adapted to inject the data signal (s E2 ) into said first section, and an output (S 2 ) of said second waveguide ( 2 ) being adapted to deliver a second data signal (s 2 ) regenerated in accordance with said second regime; said saturable absorber structure having a dimension along the first guide axis greater than its dimension along the second guide axis.
