Abstract

We present an experimental study on the ultra-narrow bandwidth tunable atomic filter with electromagnetically induced transparency at 795 nm in rubidium vapor. The filter achieves a peak transmission of 8% and a linewidth of 15 MHz. The transmission peak can be tuned within the range of the Doppler linewidth. There is just one transmission peak, all other frequencies of light cannot pass through the filter.

Theoretical study on the ultra-narrow bandwidth tunable atomic filter with electromagnetically induced transparency

Abstract To obtain the weak signal light detection from the high background noise, we present a theoretical study on the ultra-narrow bandwidth tunable atomic filter with electromagnetically induced transparency. In a three-level Λ -type atomic system in the rubidium D1 line, the bandwidth of the EIT atomic filter is narrowed to ~ 6.5 MHz . And the single peak transmission of the filter can be up to 86 % . Moreover, the transmission wavelength can be tuned by changing the coupling light frequency. This theoretical scheme can also be applied to other alkali atomic systems.

Narrowband tunable filter based on velocity-selective optical pumping in an atomic vapor

Alessandro Ceré, Valentina Parigi, Marta Abad +3 more

We demonstrate a tunable narrowband filter based on optical-pumping-induced circular dichroism in rubidium vapor. The filter achieves a peak transmission of 14.6%, a linewidth of 80 MHz, and an out-of-band extinction of >or=35 dB. The transmission peak can be tuned within the range of the Doppler linewidth of the D1 line of atomic rubidium at 795 nm. While other atomic filters work at frequencies far from absorption, the presented technique provides light resonant with atomic media, useful for atom-photon interaction experiments. The technique could readily be extended to other alkali atoms.

Ultranarrow bandwidth tunable atomic filter via quantum interference-induced polarization rotation in Rb vapor

Zheng Tan, Xianping Sun, Jun Luo +5 more

We report the experimental demonstration of an ultranarrow bandwidth atomic filter by optically induced polarization rotation in multilevel electromagnetically induced transparency systems in hot Rb vapor.With a coupling intensity of 2.3 W/cm 2 , the filter shows a peak transmission of 33.2% and a bandwidth of 10 MHz.By altering the coupling frequency, a broad tuning range of several Doppler linewidths of the D1 line transitions of 87 Rb atoms can be obtained.The presented atomic filter has useful features of ultranarrow bandwidth, and the operating frequency can be tuned resonance with the atomic transition.Such narrowband tunable atomic filter can be used as an efficient noise rejection tool in classical and quantum optical applications.

Sub-Doppler bandwidth atomic optical filter

Lincoln D. Turner, V. Karaganov, P. J. O. Teubner +1 more

We demonstrate what is to our knowledge the first atomic optical filter that uses velocity selection to achieve a passband width that is less than the Doppler width of the filtering transition. A narrow-linewidth pump laser is used to induce circular birefringence in a narrow velocity class of atoms in a dense potassium vapor for 694-nm light resonant with the 4P(3/2)-6S(1/2) transition. The filter displays a single 170-MHz passband at a peak transmittance of 9.5%. The bandwidth is an order of magnitude lower than that of previously demonstrated atomic optical filters.

Transmission characteristics of an excited-state induced dispersion optical filter of rubidium at 775.9 nm

The operation of an ultra-narrow bandwidth optical filter based on the 5P3/2 --> 5D3/2 excited-state transition in rubidium vapor is reported. The 5D3/2 state is excited by a circularly polarized pump beam at 780 nm from a diode laser. The filter displays a single 398-MHz bandwidth at a peak transmission of 9.0%, which is narrower than the Doppler bandwidth. The dependence of peak transmission on the pump intensity and cell temperature is also given.

Ultranarrow bandwidth nonlinear Faraday optical filter at rubidium D2 transition

We demonstrate a narrowband optical filter which operates on the 52S1/2 to 52P3/2 transition at 780 nm in rubidium vapor based on optical-pumping-induced dichroism combined with Faraday anomalous dispersion effects. Its peak transmission is 18.4(2)% at the 52S1/2, F = 2 to 52P3/2, F ' = 1, 3 crossover transition, whereas at the 52S1/2, F = 2 to 52P3/2, F ' = 2, 3 crossover transition the transmission is 18.6(2)%. Both transitions have a bandwidth (full-width at half-maximum of peak transmission) as narrow as 24.5(8) MHz, which is remarkably improved compared with the narrowest bandwidth as we know. This technique can also be applied to other alkali atoms.
