Abstract:
1. A method for analyzing the reliability of optoelectronic elements rapidly, comprising: (a) performing a first testing and measuring step on a plurality of optoelectronic elements by a spectrum analyzer to obtain noise equivalent power (NEP) and peak of noise power spectrum of each optoelectronic element at a frequency; (b) alternately applying positive currents and negative currents to the optoelectronic elements to form cycles; (c) performing a second testing and measuring step on the optoelectronic elements by the spectrum analyzer to obtain noise equivalent power (NEP) and peak of noise power spectrum of each optoelectronic element at the frequency; and (d) comparing the noise equivalent power (NEP) and the peak of noise power spectrum of each optoelectronic element obtained in the first testing and measuring step with the noise equivalent power (NEP) and the peak of noise power spectrum of each optoelectronic element obtained in the second testing and measuring step, thereby obtaining the optoelectronic elements having reliability problems.
