O. Blum et al., LOW-VOLTAGE-TUNABLE DISTRIBUTED-BRAGG-REFLECTOR USING INGAAS GAAS QUANTUM-WELLS/, IEEE photonics technology letters, 5(6), 1993, pp. 695-697
We report the first tunable quantum well Bragg reflector with inter-di
gitated contacts. This contacting scheme produces over 12% change in r
eflectivity for only +1 V applied voltage.
