A monolithically integrated distributed feedback (DFB) laser and traveling-wave electro-
absorption modulator (TWEAM) with ≧100 GHz -3 dBe bandwidth suitable for Non-return-to-
zero (NRZ) operation with on-off keying (OOK) is presented. The steady-state, small-signal
modulation response, microwave reflection, chirp characteristic, and both data operation
and transmission were investigated. The DFB-TWEAM was found to be an attractive
candidate for future short distance communication in high bitrates systems.
