Abstract

We present an application of the Faraday effect to produce a narrowband dichroic beam splitter using an alkali metal vapor. Two Raman beams detuned in frequency by the ground-state hyperfine splitting in Rb87 are produced using an electro-optic modulator and then separated using the Faraday effect in an isotopically pure Rb85 thermal vapor. An experimental transmission spectra for the beam splitter is presented along with a theoretical calculation. The performance of the beam splitter is then demonstrated and characterized using a Fabry–Perot etalon. For a temperature of 70°C and a longitudinal magnetic field of 80 G, a suppression of one frequency of 18 dB is achieved, limited by the quality of the polarizers.

(a) Schematic experimental setup. An electro-optic modulator (EOM) is used to create sidebands at ν ± ν m with ν m = 6.8 GHz producing light corresponding to the Raman transitions in Rb 87 , as shown in (b). The components at ν and ν + ν m are separated using the Faraday effect in a heated Rb 85 vapor cell within a solenoid. The input light is initially horizontally polarized using a polarizing beam-splitting (PBS) cube. The different frequency components are separated using a second PBS cube. The insets show schematics of Fabry–Perot etalon signals.

Fig. 2
Fig. 2

Transmission spectra at both output ports of the Faraday beam splitter. Panel (a) shows the total transmission through the cell, T h + T v , for both pure Rb 85 (solid curve) and Rb vapor with the natural isotope abundance (dashed curve). Panel (b) corresponds to the transmitted port of the beam splitter, with panel (c) corresponding to the reflected port. The temperature of the splitter is approximately 70°C, and the magnetic field is 80 G. The power of the beam before the splitter was approximately 25 μW with a waist of 1 mm. The black curve line is experimental data and the gray curve (blue online) is a theoretical calculation. The solid vertical line shows the frequency of the carrier, and the dashed line shows the frequency of the sideband, ν + ν m . Zero detuning corresponds to the weighted center of the Rb 85 and Rb 87 D 2 lines.

Fabry–Perot etalon signals (a) with the beam splitter turned off, (b) at the transmitted port of the polarizer ( T h ) , and (c) at the reflected port ( T v ) . In (a) both carrier and sideband are present, in (b) the carrier is suppressed to approximately −18 dB, and in (c) the sideband is suppressed to the noise level, leaving only the carrier.
