Figure 2: FADOF optimization and setup for the QD-atom interface description
From: Simultaneous Faraday filtering of the Mollow triplet sidebands with the Cs-D1 clock transition
(a) Transmission efficiency, ηeff(B,T), of the entire Mollow emission filtered by a Cs-Faraday filter. The centre (Rayleigh) peak passes through the filter if the temperature is too high (area to the right of the red dashed line). Experimental configuration, with 37.5 mT, is marked (white dashed line). (b) Transmission efficiency of the Mollow sidebands, optimal area for best transmission (red highlighted area). It is worth noting that the map in (a) is normalized over the total Mollow spectrum (that is Rayleigh line plus the two sidebands), while (b) is normalized over the sidebands only (that is over half of the previously used area). This means that the numbers displayed in (b) represent the actual value of sidebands transmission. (c) Sketch of the complete setup: the light from the resonantly excited QD is sent through the Faraday filter. Because all components are fibre coupled, the FADOF can be easily removed to send the QD light directly into the Fabry-Pérot inferferometer.
