Abstract

We investigate the InAlAs/InGaAs metamorphic HEMT on GaAs substrate as a harmonic optoelectronic mixer. The fabricated metamorphic HEMT simultaneously performs photodetection at 1.55μm lightwave and harmonic optoelectronic up-conversion into millimeter-wave band. By changing the bias conditions of the HEMT, the harmonic optoelectronic mixing efficiency can be selectively enhanced while suppressing undesired mixing components. The metamorphic HEMT as a harmonic optoelectronic mixer is a promising candidate that can simplify the base station architecture in fiber-optic millimeter-wave transmission systems.
