In a previous Letter [ Tsang and Psaltis, Opt. Lett. 31, 2741 (2006) ], we assert that the total reflection coefficient of two dielectric slabs goes to zero in the limit of single-waveguide resonance. A more careful derivation shows that this is not the case. The correct condition in which reflectionless evanescent-wave amplification can be achieved by two dielectric planar waveguides is derived in this Erratum.
