Paper Abstract

Responsivity is a very important parameter in characterizing the photo-detectors and optical receivers. It is defined as the ratio of photo-current generated to the amount of optical power incident onto the photo-detector. Actual measurement of the optical power being transmitted into the pigtailing fiber is not straight forward and contributes most of the error in the responsivity measurements. In this paper, a repeatable responsivity measurement method is discussed. The essence of this method is to measure the optical power first and attempt to achieve 100% coupling between this optical source fiber and the photo-detector fiber. Using a multimode fiber for the source to couple into the multimode pigtailed photo-detector gives inconsistent measurements and the results are not repeatable. Experiments have been performed using single mode fiber as the source for responsivity measurements, the result has been found to be very consistent. This method is being used as standard operating procedure for manufacturing.
