Sažetak
In this paper photodiode response to different excitations, and square, sine and triangular input waveforms is analyzed. Excitations are obtained with single wavelength LE Diode with pulse voltage applied (10kHz – 100kHz). Results for different input pulses have been analyzed. Silicon PD used for measurements has spectral range from 430 nm to 900 nm with high signal to noise ratio. Measurement results show dependence on input signal waveform as well as incident lights wavelength. Significant dependence of PD voltage responses local derivative on incident wavelength has also been assessed. Difference in local derivative could be used to differentiate between incident wavelengths. Current density can be calculated for each incident wavelength as well as I-V, V-t and I-t characteristics in order to find distinguishing features of each wavelength response.
