We have studied the coherence length of the electronic wavefunction in an \(\operatorname{InGaAs} / \mathrm{In}\) superlattice structure prepared by chemical beam epitaxy. The sample, a p-i-n structure, was processed to form a waveguide modulator, and transmittance and photocurrent measurements were
