LLM‐Assisted Design of Ultralow‐κ$\kappa$ Chalcogenides

Advanced Science, EarlyView.
An AI assisted, physics guided workflow accelerates the discovery of ultralow thermal conductivity materials by combining Bayesian optimization, evidence conditioned LLM reasoning, and automated physics‐based validation. The framework uncovers dynamically stable Ag based chalcogenides with ultralow thermal conductivity and promising thermoelectric ...

Analytical Expression for the Modulation Bandwidth of a Reflective Semiconductor Optical Amplifier

12th International Conference on Fiber Optics and Photonics, 2014
An analytical formula for the bandwidth of a reflective semiconductor optical amplifier (RSOA) operated by directly modulating its injection current is derived. The formula allows gaining insight into the dependence of the RSOA modulation bandwidth on the main semiconductor parameters.

Model simulations of a reflective semiconductor optical amplifier

SPIE Proceedings, 2006
A reflective semiconductor optical amplifier is modeled using a rate equation for the inversion and an expression for the outgoing field in terms of the incoming field and the instantaneous inversion, for both the cases of linear and nonlinear gain, while assuming modulation speeds well below the round-trip frequency.
