Measurement & Calibration Procedure for the Characterization of the Scattering Parameters in Microwave Fiber-Optic Devices

A new measurement procedure is developed for the determination of optoelectronic scattering parameters in fiber-optic devices working in microwave modulating frequency range. The measurement scheme is based on a microwave network analyzer and optoelectronic transducers to determiine the optical parameters by the use of corresponding electrical parameters. The application of the TMR (Through, Match, Reflect) calibration procedure for optical measurements is straightforward, which requires for the realization of the needed optical standards only commercially available elements. The error removal can be performed in a wide modulating frequency range both in transmission and reflection measurements. The validity of this measurement calibration procedure is demonstrated by some measurement examples.
