Abstract: A comparison is presented between optical bistability in laser amplifiers and in passive Fabry-Perot cavities. The basis for comparison is afforded by a new analysis of optical amplifiers ...

The gradual emission state and photocurrent transitions are simulated and are in excellent agreement with experiments. In contrast, in a medium-chirped laser a photocurrent and emission-state ...

Crystalline perovskites in an optical cavity exhibit nonlinear optical effects under continuous-wave excitation, including optical bistability and polarization rotation. Phonon polariton quasi ...

Three-dimensional (3D) lead halide perovskites have emerged as a promising class of coordination polymers for solar cells, photodetectors, and light-emitting devices. These compounds thus far comprise ...

Our work advances the theory of neutral evolution, paying particular attention to how the holistic fitness landscape structure shapes the process of evolution and gives rise to emergent evolutionary ...

To fight infections and cancer, T cells must selectively recognize low levels of foreign peptides from pathogens or cancer cells, but the mechanisms that enable these properties remain unclear. Using ...
