Variable spectral filter based on optically saturated selective reflection Academic Article uri icon


  • We have studied the selective reflection from glass-rubidium vapor interface at a large incidence angle in pump-probe experiment. The linear reflectivity can be more than 0.9 in a narrow spectral range (several GHz) at the blue side of the atomic resonance. The effect can be called the reduced total selective reflection. The reflectivity has been decreased two times due to the optical saturation. The obtained results can be used to develop a variable optical filter or optical switcher. Our estimations show that switching time can be less than the natural lifetime of the excited state. We suggested a multi-reflection scheme to increase the contrast of the variable spectral filter. 2011 Pleiades Publishing, Ltd.
