Correction technique for on-chip modulation response measurementsof optoelectronic devices

A new and accurate error correction technique for on-chip intensity modulation response measurements of high-frequency optoelectronic devices is presented. Mathematical expressions for the different sources of errors that exist in the measurement system are derived. The new correction technique applied to the modulation response measurement of a strained quantum well laser diode shows excellent agreement with the theoretically expected result. Simulation results for a small-signal circuit model of the laser diode show excellent agreement with the measured input reflection coefficient S₁₁ and the modulation response S₂₁. With the corrected modulation response measurement, more accurate parameters for this model are extracted
