Continuously tunable, precise, single frequency optical signal generator.
To realize a genuine CW optical frequency synthesizer, a continuously tunable single-frequency CWlaser has been employed to track precisely any arbitrary component of a wide bandwidth phase-stabilized optical comb. We demonstrate experimentally two fundamental aspects of optical frequency synthesis, namely, precise setting of the laser frequency at an arbitrary pre-determined value, and continu...
متن کاملA New Analog-based LO Harmonic Rejection Technique with Tunable Notch Frequency
An effective technique for mixer LO harmonic rejection in a SAW-less wideband receiver front-end is proposed. The proposed technique provides a tunable notch that can be placed at any frequency like mixer LO harmonics, to avoid the aliasing in baseband after mixing. An analog LC notch is used in a cascode transconductor, and it can reject one of the 3rd or 5th harmonics. T...
متن کاملTunable high - purity microwave signal generation from a dual - frequency VECSEL at 852 nm
We demonstrate the dual-frequency emission of a diode-pumped vertical external-cavity semiconductor laser operating at 852 nm, dedicated to the coherent population trapping of cesium atoms for compact atomic frequency references. It is based on a single laser cavity sustaining the oscillation of two adjacent, cross-polarized, modes. The output power reaches 10 mW on each frequency. The frequenc...
متن کاملFrequency-tunable micromechanical oscillator
An experimental method, employing a scanning tunneling microscope ~STM! as an actuator and a scanning electron microscope ~SEM! as a motion detector, was developed to study microelectromechanical systems ~MEMS! and has been applied to study microfabricated cantilever beams. Vibrations actuated by an ac voltage applied to the piezodrive are transferred to the sample by the STM tip, which also pr...
متن کاملThermal frequency shift and tunable microwave absorption in BiFeO3 family
Tunable frequency is highly sought-after task of researcher, because of the potential for applications in selecting frequency, absorber, imaging and biomedical diagnosis. Here, we report the original observation of thermal frequency shift of dielectric relaxation in La/Nd doped BiFeO3 (BFO) in X-band from 300 to 673 K. It exhibits an unexpected result: the relaxation shifts to lower frequency w...
