Abstract
In this paper, we present a new broadband light source covers 1280-1380nm region for application in a wavelength division multiplexing biomedical fiber-optic Bragg grating spectra reflective sensors. We cascade two optical amplifiers for achieving the 100nm broadband light source. The cascaded two optical amplifiers are praseodymium fluoride fiber amplifer (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 100nm from 1280nm to 1380nm with driving current 50mA and pumping power 885mW of MQW-SOA and PDFA respectively.
