Abstract :
Various mixed signal ASICs have been designed to address 40 Gb/s optical transmission experiment needs, and realized specific research transmitters. These circuits have been fabricated using a self-aligned InP DHBT process. Three transmitters have been assembled using these IC: i) an EAM-based; ii) a DDA-based; iii) a PSBT/DPSK transmitter. Design and characterization of these circuits are reported.
