Publikováno v: Journal of Integrated Circuits and Systems. 15:1-5

In this work we present an InGaAs/InAlAs heterostructure lattice matched with InP that holds two leaky electronic states in the continuum. An optical analogy with Bragg mirrors is used to explain the origin and the desired characteristics of the leak
