Implementation of A 1280nm-1380nm Light Source Reflective Spectrum Measurement of Biomedical Fiber Sensors

Abstract

In this paper, we present a new broadband light source covers 1280-l380nm region for application in a wavelength-division multiplexing biomedical fiber-optic Bragg grating spectra reflective sensors. We cascade two optical amplifiers for achieving the 1 00nm broadband light source. The cascaded two optical amplifiers are praseodymium fluoride fiber amplifier (PDFA) and multiple quantum well optical semiconductor amplifier (MQW-SOA), respectively. The optimal driving current of MQW-SOA and the optimal pumping power of PDFA are experimentally searched. We find the bandwidth can reach lOOnm from l280nm to 1380nm with driving current 50mA and pumping power 885mW of MQW-SOA and PDFA, respectively.
