Abstract

This paper reports what is to our knowledge the first demonstration of Zeeman absorption Faraday anomalous dispersion optical filter (hereafter abbreviated to FADOF/Zeeman). The mutual relations among passband, tuning capability, cell temperature and magnetic field of FADOF/Zeeman have been studied theoretically and experimentally. The results showed that the single passband of FADOF/Zeeman was about 1 GHz, which is 3 times less than the passband of FADOF. The tuning capability was about 1 GHz/0.01 T.

Demonstration of Faraday anomalous dispersion optical filter with reflection configuration

Yi Liu, Baodong Yang, Junmin Wang +3 more

Abstract A narrow linewidth Faraday anomalous dispersion optical filter (FADOF) with reflection configuration is achieved for the first time based on the cesium (Cs) ground state 6S1/2 to the excited state 6P3/2 transition at 852 nm. Compared with the conventional FADOF with transmission configuration, reflection-type FADOF can greatly improve the transmittance of optical filter under the same experimental parameters, because it allows signal light to go and return through the atomic vapor cell. In our experiment, peak transmittance at Cs 6S1/2 F = 4–6P3/2 transition is 81% for the reflection-type FADOF, and while 54% for the transmission-type FADOF when the temperature of Cs vapor cell and the axial magnetic field are 60 °C and 19 G. The idea of this reflection-type FADOF design has the potential to be applied to the FADOF operating between two excited states to obtain higher transmittance.

Isotope ^87Rb Faraday anomalous dispersion optical filter at 420 nm

Ling Li, Gang Bi

We demonstrate a Faraday anomalous dispersion optical filter (FADOF) operating on 5S(1/2)-6P(3/2) transition at 420 nm with a 5 cm long cell of 96.5% enriched 87Rb and measure the transmission as a function of the magnetic field and temperature. The isotope 87Rb FADOF achieves a peak transmission of 98% with a bandwidth of 2.5 GHz when the temperature of the isotope 87Rb cell is 280°C and the magnetic field is 500 G. The corresponding equivalent noise bandwidth is 5.9 GHz. The isotope 87Rb FADOF is applied to submarine communications, is used as the laser frequency stabilization for some atomic lines, and is also used as the pump laser in four-level Rb active optical clock.

Optical filtering characteristic of potassium Faraday optical filter

Yundong Zhang, Xiaoling Jia, Zuguang Ma +1 more

An ultra-narrow bandwidth potassium Faraday anomalous dispersion optical filter (FADOF) at the D/sub 2/ line is studied theoretically and experimentally. The effect of temperature on the characteristics of the potassium Faraday filter is discussed and the transmission versus temperature is given. Our research results show that the transmission of the K-FADOF reaches nearly 90% with a bandwidth of only 1.5 GHz. To meet different requirements, K-FADOF can operate at line-center or in the line-wing by changing the working parameters.

Faraday anomalous dispersion optical filter with a single transmission peak using a buffer-gas-filled rubidium cell

Xiaobo Xue, Zhiming Tao, Qinqing Sun +5 more

A Faraday anomalous dispersion optical filter (FADOF) with a single transmission peak is achieved by using a buffer-gas (argon, 2 Torr)-filled rubidium cell. At room temperature, the transmission is 0.2% and the bandwidth of the transmission peak is 0.65 GHz. At a temperature of 63° C, the transmission rises to a maximum of 30.6%, with a bandwidth of 1.41 GHz. This FADOF may replace the use of interference filters or virtually imaged phased arrays in imaging modalities.

Proposed solid-state Faraday anomalous-dispersion optical filter

Weibin Lin, Zong‐Quan Zhou, Chuan-Feng Li +1 more

We propose a Faraday anomalous dispersion optical filter (FADOF) based on a rare-earth ion doped crystal. We present theoretical analyses for the solid-state FADOF transmission. Our theoretical model predicts a maximum transmission efficiency of $71%$ and a double-peaked transmission spectrum with a bandwidth of 6 GHz under current experimental conditions. Our proposal may have important applications in optical communications.
