Device for generating a modulation of an optical signal comprising electro-absorption modulators

Abstract

The invention relates to a device for generating a modulation (10) of an optical signal comprising: a first electro-absorption modulator (36) comprising: a first P-doped semi-conductor area (38), a first N-doped semi-conductor area (40), and a first active portion (42), a second electro-absorption modulator (50) comprising: a second P-doped semi-conductor area (52) in electric contact with the first N-doped semi-conductor area (40), a second N-doped semi-conductor area (54), and a second active portion (56), and a connector for introducing electric modulation (46), characterized in that the connector for introducing electric modulation (46) is in contact with the first N-doped semi-conductor area (40) and the second P-doped semi-conductor area (52).
