Abstract : Superluminescent diodes with broad emission spectrum, which makes them insensitive to optical feedback and hence most suitable for massively interconnected systems, have been fabricated with an integrated modulator. The superluminescent has high emission power (up to 30mW) which makes possible systems with many levels of branchings. The modulator is based on carrier induced absorption and shows a very high modulation efficiency. In addition to device fabrication and experimental measurements which shows a direct modulation bandwidth beyond 1GHz, the static and dynamics of the superluminescent diode, with and without the integrated modulator, have been analyzed. It is shown that by using quantum well materials much improvement in modulation efficiency as well as bandwidths in the multigigahertz range can be accomplished.
