Abstract

Performance-limiting asymmetric distortion is observed in the spectra of fundamental pulses transmitted through GaAsAl0.9Ga0.1As multilayer waveguides designed for surface-emitted second-harmonic generation. This behavior is attributed to refractive-index changes resulting from the accumulation of free carriers created by two-photon absorption in the GaAs layers. Numerical simulations of the intensity-dependent spectra by use of the separately measured two-photon absorption coefficient are shown to be in good agreement with the observed spectra.

Room-temperature band-edge luminescence resulting from the subbandgap fundamental λ1.5 μm, measured above the input facet of the waveguide. The intensity dependence confirms that carrier generation is dominated by TPA. The peak emission wavelength and the high-energy tail verify minimal heating.
