Query: On Development of Efficient Data Acquisition Systems and Parameter
  Extraction Technique for DFB Lasers   Distributed Feedback Laser plays a key role as a light source component in
optical fiber communication systems ranging from metro, long-haul to submarine
one thanks to its competitive features of superior narrow spectral width and
wavelength cohesion. Characterizing such lasers via obtaining their electrical
and spectral data and extracting their internal parameters therefore remains a
critical task in designing and troubleshooting optical fiber systems. This
paper presents first an agile framework for a rapid collection of laser data
via automatic measurement and second an efficient approach for extracting laser
internal parameters.
