Ultrahigh-noise rejection optical filter

D. J. Dick, T. M. Shay

Published Jun 1, 1991• 138 citations
Publisher

Abstract

We present the results of what is to our knowledge the first experimental demonstration of a Faraday anomalous dispersion optical filter. This optical filter has a measured bandpass of 1 GHz, a transmission of 0.63, and an out-of-band rejection of 10(5).

The Rb 780-Nanometer Faraday Anomalous Dispersion Optical Filter: Theory and Experiment

Bing Yin, L. S. Alvarez, Thomas M. Shay

The Faraday anomalous dispersion optical filter may provide ultra-high background noise rejection for free-space laser communications systems. The theoretical model for the filter is reported. The experimental measurements and their comparison with theoretical results are discussed. The results show that the filter can provide a 56-dB solar background noise rejection with about a 2-GHz transmission bandwidth and no image degradation. To further increase the background noise rejection, a composite Zeeman and Faraday anomalous dispersion optical filter is designed and experimentally demonstrated.

A study of the physical properties of Zeeman absorption faraday anomalous dispersion optical filter

Duan Ming-Hao, Yimin Li, Tang Jun-xiong +1 more

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.

Faraday anomalous dispersion optical filter for the Cs 455 nm transition

B. Yin, Thomas M. Shay

The performance of a Faraday anomalous dispersion optical filter operating on the Cs 455-nm transition is calculated. The results show that the filter can provide high transmission (0.96), very narrow pass bandwidth (0.9 GHz), and low equivalent noise bandwidth (3.3 GHz) under optimum filter operational conditions. The optimum filter conditions also suppress the transmission of the Cs 459-nm transition.>

Ultranarrow Faraday rotation filter at the Rb D_1 line

Joanna A. Zielińska, Federica A. Beduini, Nicolas Godbout +1 more

We present a theoretical and experimental study of the ultranarrow bandwidth Faraday anomalous dispersion optical filter operating at the rubidium D1 line (795 nm). This atomic line gives better performance than other lines for key figures of merit, e.g., simultaneously 71% transmission, 445 MHz bandwidth, and 1.2 GHz equivalent-noise bandwidth.

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.
