WebApr 1, 2024 · Exciton–polaritons in optical cavities exhibit strong nonlinearities predominantly because of the third-order Kerr-like interactions mediated by the excitonic component. Under quasi-resonant excitation, depending on the energy of the incident laser, it results in the optical limiting or bistable behavior. The latter phenomenon is manifested … WebIn the bistable regime (y = y 2, y c, or y 3 ), P st (x) has two peaks and V (x) two minima. A minimum in V (x) above the absolute minimum can be thought of as a metastable state. In Fig. 2.7-1a the upper branch between y ↓ and y c and the lower branch between y c and y ↑ are metastable states.

WebIn this work, we numerically demonstrate optical bistability with bound states in the continuum in a simple one-dimensional Si photonic crystal. The designed structure supports bound states in the continuum, producing an ultrahigh quality factor without tough fabrication conditions. WebLooking for bistable optical device?

WebA multimode integrated optical bistable switch using a LiNbO 3 phase modulator in a noncavity configuration was constructed and tested. Bistability and discriminator operation were observed in this device using a He–Ne laser. © 1978 Optical Society of America Full Article PDF Article More Like This WebIn optics, optical bistability is an attribute of certain optical devices where two resonant transmissions states are possible and stable, dependent on the input. Optical devices with a feedback mechanism, e.g. a laser, provide two methods of achieving bistability . WebOptical bistable operation in a single nanocavity permits optical read–write memory operation, which opens the possibility of an integrated optical logic circuit on a single … how do bus bars work
