Abstract :
Switching operation in an intersectional-type field effect multiquantum-well optical switch was observed for the first time from light reflection caused by the electric-field-induced refractive index variation and absorption coefficient change. The authors report switching operation in a GaInAsP/InP MQW ridge waveguide structure with an intersection angle of 4°. Polarisation dependent properties originating from the quantum-well structure were also observed
