In this work we present an InGaAs/InAlAs heterostructure lattice matched with InP that holds two leaky electronic states in the continuum. An optical anal-ogy with Bragg mirrors is used to explain the origin and the desired characteristics of the leaky electronic state. Multipass waveguide absorption measurements were performed and theoretical calculations used to determine the energy levels involved in the optical transitions. The comparison between the theoretical and experimental oscilla-tor strength shows the good optical quality of the sample.
