WebOpen spectrum.lsf file and run the script. The spectrum of the DFB laser for a flat gain (FWHM = 1000nm) and a bias current of 28mA is measured by the ‘OSA_1’ and plotted below. The simulation result corresponds well to the result reported in the reference [1]. In the script, increase the bias current to 63mA and run the script again. WebDistributed Bragg Reflector Laser Similar to DFBs, Distributed Bragg Reflector (DBR) Lasers incorporate an internal grating structure. However, whereas DFB lasers incorporate the grating structure continuously along the active region (gain region), DBR lasers place the grating structure(s) outside this region (see Figure 4).
