WebThen, by using the mentioned results, the effects of spatial chirped grating on the dynamic large signal response is investigated. DFB LASER STRUCTURE. In order to study the fundamental characteristics of a DFB laser, a DFB-laser has been considered to be uniform (conventional) and non-uniform (linear chirp) grating operating at 1550 nm. WebAug 28, 2024 · Measured device spectra can be fitted to the TMM model using a least squares curve fitting method. In this case, the form of the grating chirp is assumed, e.g., unchirped or linear blue-chirp. The coupling coefficient and the maximum and minimum effective index values at the grating ends are then left as free parameters to perform the fit.
