متن کاملNonlinear suppression of time reversals in PT -symmetric optical couplers
We reveal a generic connection between the effect of time reversals and nonlinear wave dynamics in systems with parity-time (PT ) symmetry, considering a symmetric optical coupler with balanced gain and loss where these effects can be directly observed experimentally. We show that for intensities below a threshold level, the amplitudes oscillate between the waveguides, and the effects of gain a...
متن کاملOptical solitons in PT -symmetric nonlinear couplers with gain and loss
We study spatial and temporal solitons in the PT symmetric coupler with gain in one waveguide and loss in the other. Stability properties of the highand low-frequency solitons are found to be completely determined by a single combination of the soliton’s amplitude and the gain-loss coefficient of the waveguides. The unstable perturbations of the high-frequency soliton break the symmetry between...
متن کاملOptical fiber couplers for precision spaceborne metrology.
We describe the optical and mechanical design, construction philosophy, and testing of a pair of matched, spaceflight-qualified fiber couplers. The couplers were developed for the LISA Pathfinder mission but are relevant for other applications-both on ground and in space-where a robust fiber coupler with well-controlled beam parameters and stable beam pointing is required. This particular imple...
