Photonics, 11(5), 47610.3390/photonics11050476https://hdl.handle.net/10433/22688We analyze the two classic methods for chirped Integrated Bragg Gratings (IBGs) in Silicon on-Insulator technology using the transfer matrix method based on the effective refractive index (neff) technique, which translates the geometry of an IBG into a matrix of neff depending on the wavelength. We also implement a procedure that allows engineering of the chirped IBG parameters, given a required bandwidth (BW) and group delay (GD). Finally, a complementary method for designing chirped IBG is proposed, showing a significant improvement in the bandwidth of the device or a moderation in the variation of the geometrical parameters of the grating.application/pdfenAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Integrated Bragg GratingSilicon photonicsChirp functionGroup delayEffective refractive indexjournal articleopen access
