[Show abstract][Hide abstract] ABSTRACT: We have proposed an equivalent electric circuit model of p-i-n photodiode including the transit-time effect for performance evaluation of optical systems through the aid of a SPICE-like circuit simulator. No model-dependent close-form expression is necessary in our model. Its validity is shown for the analysis of frequency response in simplified p-i-n photodiodes with different lengths of i-region under uniform or nonuniform illumination. Its application to eye-diagram analysis is demonstrated also.
