Abstract
A monolithically integrated distributed feedback (DFB) laser and
traveling-wave electro-absorption modulator (TWEAM) with ${\geq} 100$ 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.
