The study of in-line DFB tunable laser based on REC technique

We studied the in-line DFB tunable laser based on REC technique. We mapped the contour lines of the P-I contour diagram of this in-line tunable laser into the wavelength-current contour map. And the maximum output power is obtained. Also the tuning currents are obtained. Firstly, we simulated the P-I contour as well as wavelength-current contour. Secondly, we experimentally demonstrated the mapped contour.
