Optoelectronic frequency response measurement of photodiodes by using high-extinction ratio optical modulator

摘要

References(6) Cited-By(4) We propose a measurement method of photodetector frequency response. This technique is based on a heterodyne principle, where a high-extinction ratio Mach-Zehnder modulator is used to generate a two-tone lightwave as a stimulus signal up to millimeter-wave frequency bands. Our proposing method can provide a relatively short traceability chain to optical and electric power standards.
