| 摘 要： | We present a new type of optical filter with an ultra-narrow bandwidth and a wide field-of-view （FOV）. This kind of optical filter consists of one-dimensional photonic crystal （PC） incorporating an anomalous-dispersion-material （ADM） with, for instance, an anomalous dispersion of 6P3/2←6S1/2 hyperfine structure transition of a caesium atom. The transmission spectra of optical filters are calculated by using the transfer-matrix method. The simulation results show that the designed optical filter has a bandwidth narrower than 0.33GHz and a wide FOV of ±30°as well. The response of transmission spectrum to an external magnetic field is also investigated. |

| Abstract: | We present a new type of optical filter with an ultra-narrowbandwidth and a wide field-of-view (FOV). This kind of opticalfilter consists of one-dimensional photonic crystal (PC)incorporating an anomalous-dispersion-material (ADM) with, for instance, an anomalous dispersion of$6$P$_{3/2}leftarrow6$S$_{1/2}$ hyperfine structure transition of acaesium atom. The transmission spectra of optical filters arecalculated by using the transfer-matrix method. The simulationresults show that the designed optical filter has a bandwidth narrower than 0.33GHz and a wide FOV of$pm30^{circ}$ as well. The response of transmission spectrum toan external magnetic field is also investigated. |
