Coherence Phenomena in Nonlinear Coupled Oscillators with the Optical Parametric Process

چکیده
We theoretically and experimentally demonstrate coherence phenomena of nonlinear coupled oscillators in optical parametric process. The mode splitting in transmission spectra of phase-sensitive optical parametric amplifier is observed. Especially, we show a very narrow dip and peak, which are the shape of δ function, appear in the transmission profile. The origin of the coherence phenomenon in this system is the interference between the harmonic pump field and the subharmonic seed field in cooperation with dissipation of the cavity. This system is closely relate to electromagnetically induced transparency.

متن کاملTheory of backward distributed-feedback optical parametric amplifiers and oscillators
We derive a coupled-wave theory for backward phase-matched optical parametric amplifiers and oscillators in a dielectric modulated nonlinear optical material. Unlike a forward phase-matched distributed-feedback optical parametric oscillator, a backward oscillator of this type can have high-threshold gap modes at Bragg resonance and low-threshold detuned modes. In addition to the structure feedb...
متن کاملOptical parametric oscillators pumped by population-trapped atoms.
We describe an optical parametric oscillator that is pumped by population-trapped atoms that are prepared with maximum coherence. The oscillator is based on the use of an effective nonlinear susceptibility that is of the same order as the linear susceptibility. Because the parametric gain is obtained in a single coherence length, the gain bandwidth can exceed the degenerate frequency. In Pb vap...
متن کاملExperimental observation of the amplitude death effect in two coupled nonlinear oscillators
The amplitude death phenomenon has been experimentally observed with a pair of thermo-optical oscillators linearly coupled by heat transfer. A parametric analysis has been done and compared with numerical simulations of a time delayed model. The role of the coupling strength is also discussed from experimental and numerical results.
متن کاملSelf-induced thermal effects and modal competition in continuous-wave optical parametric oscillators
We present a model of quasi-phase-matched continuous-wave optical parametric oscillators that accounts for self-induced heating of the photorefractive crystal and modal interaction through pump depletion. The model allows the temperature and therefore the refractive index of the nonlinear medium to vary in the radial and longitudinal dimensions as a result of local absorption of the optical pow...
