摘要：
We have produced a nonabsorbing surface-normal optical modulator operating at 1.06 μm (e.g., for a high-power Nd-YAG pump laser) which has a relative transmission change of 16% for -1 to 1 voltage swing. The structure is a GaAs-AlAs dielectric mirror with alternating n- and p-type δ doping at each interface. Doping selective contacts are made to the sample so that an applied voltage appears equally across each period of the device, yielding a strong field which changes the index of the GaAs and hence shifts the mirror.
