An analytical model for two-pass optical amplifier with arbitrary beams overlap has been developed which generalized the classical theory of Frantz-Nodvik for single pass amplifier. The effect of counterpropagating beams on gain and output energy fluence included in the model. Moreover, the appropriate limiting relations for two special cases of weak input signal and saturation state of the amp...
Abstract This article mainly focuses on important quantum phenomenon called entanglement arising the nonlinearity property. study uses a unique approach in which transistor effect (third-order nonlinearity) entangled microwave photons are created cryogenic low-noise amplifier (LNA). For analysis, Hamiltonian of designed LNA (containing two coupled oscillators) is derived, and then, using dynami...
In this workwe derive the general conditions for obtaining nonreciprocity inmulti-mode parametrically-coupled systems. The results can be applied to a broad variety of optical,microwave, and hybrid systems including recent electroand opto-mechanical devices. In deriving these results, we use a graph-basedmethodology to derive the scatteringmatrix. This approach naturally expresses the terms in ...
The computed maximum a v a i l a b l e g a i n (MAG) and c u r r e n t g a i n (Ih211) from t h e de-embedded s-parameters show t h a t MAG i s unaffected by o p t i c a l i l l u m i n at i o n , however, Ih211 increases by more than 2 dB under o p t i c a l i l l u m i n a t i o n o f 1.5 mW. g a i n c u t o f f frequency (F t) o b t a i n e d by e x t r a p o l a t i n g t h e MAG and Ih21 I...
We performed a novel phase-sensitive microwave reflection experiment which directly probes the dynamics of the Josephson plasma resonance in both the linear and the nonlinear regime. When the junction was driven below the plasma frequency into the nonlinear regime, we observed for the first time the transition between two different dynamical states predicted for nonlinear systems. In our experi...
