APPARATUS FOR MEASURING CARRIER LIFETIME OF SEMICONDUCTOR PHOTOEMITTER

摘要

PURPOSE:To provide an apparatus for measuring carrier lifetime simply and in a short time without being influenced by floating capacitance regardless of the packaging form of a semiconductor photoemitter under test. CONSTITUTION:A pump laser 11 is modulated by the electric signal of a network analyzer 12, where an optical output of the pump laser 11 is injected into a semiconductor photoemitter 10 under test and converted into an electric signal by a photoreceptor 13 through the optical modulation of the photoemitter 10, thereby being inputted into the network analyzer.
