Abstract

We characterize a strongly anisotropic waveguide consisting of alternating 80 nm layers of n+-InGaAs and i-AlInAs on InP substrate. A strong increase in the transverse magnetic (TM) reflection at λ = 8.4 μm corresponds to a characteristic low-order mode cutoff for the left-handed waveguide. The subsequent decrease of TM reflection at λ = 11.5 μm represents the onset of right-handed no-cutoff light guiding. Good qualitative agreement is found when the experimental results are compared to finite element and transfer-matrix frequency domain simulations.
