Electroabsorption modulators combining Franz-Keldysh effect and quantum confined Stark effect have been monolithically integrated with tunnel-injection quantum-well distributed feedback lasers using a quantum well intermixing method.Superior characteristics such as extinction ratio and temperature insensitivity have been demonstrated at wide temperature ranges.
