Monolithically Integrated 100 GHz DFB-TWEAM

Abstract

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> A monolithically integrated distributed feedback (DFB) laser and traveling-wave electro-absorption modulator (TWEAM) with <formula formulatype="inline"><tex Notation="TeX">${\geq} 100$</tex></formula> GHz <formula formulatype="inline"> <tex Notation="TeX">${-}3$</tex></formula> 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. </para>
