Author(s): Rajesh Kumar Yadav, J. Aneesh, Rituraj Sharma, P. Abhiramnath, Tuhin Kumar Maji, Ganesh Ji Omar, A. K. Mishra, Debjani Karmakar, and K. V. Adarsh The nonlinear optical absorbance of conventional materials is very weak, yet its magnitude dominates device performance in, for example, optical limiting and pulse shaping. Therefore, achieving a strong nonlinear optical response is a longstanding goal. The authors propose charge transfer between donor and acceptor materials as a means to greatly enhance nonlinear response, toward the realization of high-performance optical limiters. Excellent agreement between experiment and theory for a test hybrid material validates the idea, and guides the design and fabrication of an actual liquid-cell-based absorptive optical limiter, which outperforms benchmark devices.
