DWDM Demultiplexer Using Compound Optical Ring Resonator with Fiber Bragg Grating

The paper reports a theoretical study on the effect of grating period and loop length of optical DWDM demultiplexer using compound ordinary optical ring resonator with fiber Bragg grating. For the results, changing the grating period and optical paths can adjust the center wavelength of pass-band and narrow spacing bandpass peaks (channels)
