This paper describes quantum confined Stark effect(QCSE) tuning characteristics of InGaAsP multiple quantum well(MQW). The result of QCSE static tuning was 125%/V and the speed of wavelength conversion, which is one of dynamic tuning characteristics, due to QCSE was faster than 1 nS. The results show a possible 1550nm multiple channel source using quaternary/quaternary MQW InGaAsP/InP QCSE tuning for dense wavelength division multiplex(DWDM) systems and 140 GHz channel spacing and 32 nm channel selection bandwidth
