“…For low power systems, especially in microstrip technology, semiconductor switches are common circuit elements [6]. Electro-optical, acusto-optical, magneto-optical and nonlinear effects are used for switching and amplitude modulation [7,8,9] in microwaves and optics. In particular, electro-optical Mach-Zehnder interferometer is a typical elements in optical circuits [10].…”

We propose and analyze a multifunctional THz device which can operate as a tunable switch and a filter. The device consists of a circular graphene nanodisk coupled to two nanoribbons oriented at 90 • to each other. The graphene elements are placed on a dielectric substrate. The nanodisk is magnetized by a DC magnetic field normal to its plane. The physical principle of the device is based on the propagation of surface plasmon-polariton waves in the graphene nanoribbons and excitation of dipole modes in the nanodisk. Numerical simulations show that 0.61T DC magnetic field provides transmission (regime ON) at the frequency 5.33 THz with the bandwidth 12.7% and filtering with the Q-factor equals to 7.8. At the central frequency, the insertion loss is around -2 dB and the reflection coefficient is -43 dB. The regime OFF can be achieved by means of switching DC magnetic field to zero value or by switching chemical potential of the nanodisk to zero with the ON/OFF ratio better than 20 dB. A small central frequency tuning by chemical potential is possible with a fixed DC magnetic field.

“…The copropagating polarization spectroscopy setup is used for examining the idea of using SFM to remove recoil effect to demonstrate maximum achievable enhancement. The created light shift or AC Stark effect changes the fluorescence spectrum and cause shift in the center wavelength [12][13][14][15]. Calibration of the center wavelength shows nonlinearity in light shift error signal amplitude [13].…”

Recoil effect is one of the limiting factors of signal amplitude in many spectroscopic applications due to creating light shift or AC Stark effect. Doppler shift of the Recoil velocity of the pumped atoms reduces their absorption efficiency. Synchronous Frequency Modulation or chirping of the pump laser enhances optical pumping and amplitude of the fluorescence signal. Results of this paper demonstrate significant enhancement of the fluorescence signal and the symmetry of the signal.RECEIVED

This paper introduces a magnetically quiet environment where the magnetic-field noise is actively suppressed using an optically pumped potassium magnetometer. In a large dynamic range of Earth’s magnetic fields, the magnetic-resonance signals of potassium are completely separated in frequency, and we experimentally demonstrate that one of them could be used to measure and compensate magnetic-field noise. The magnetic-field noise floor after stabilization is ∼100 fT/Hz under a bias field ranging from 20 to 100 μT. This method could be useful for fundamental-physics experiments and biomedical sciences where a large dynamic range of quiet magnetic fields is needed.
