Abstract :
We observed distinct nonlinear behaviors of bandwidth degradation in low-temperature-grown-GaAs based traveling-wave-photodetectors under long wavelength (∼1300 nm) operation. The disclosed unique material properties of LTG-GaAs at different excitation wavelengths are important for its applications in ultrafast optoelectronic and understanding its carrier dynamics in the defect states.
