Fig. 9From: Integrated transmitter devices on InP exploiting electro-absorption modulationSchematic of the data transmission setup (left); optical eye diagrams recorded in two orthogonal polarizations at the receiver side (right). The extinction ratios are 2.5 and 7 dB, and the bit rate 20 Gbit/s per polarization. The upper eye corresponds to the first EAM (X-pol), the lower eye to the second EAM (Y-pol)Back to article page
