WebBasically, an elementary Bragg grating comprises a periodic refractive index (RI) modulation inside an optical waveguide core. The narrow-band reflection signal resulting from constructive interference of the reflected waveguide mode at the periodic Bragg grating planes is defined as the Bragg wavelength according to (1) WebThe Bragg mirror is needed to maximize the electromagnetic (e.m.) transmission from the input waveguide to the cavity. Figure 3 shows the optical transmission/reflection and e.m. energy density curves obtained.
