Optical Power Limiting

A series of mixed-ligand diimine–halide and diimine–dithiolene clusters based on the Mo3S7 core have been synthesized. Their optical limiting behavior was assessed by Z-scan techniques, and compared to that of a dithiolene Mo2O2S2-based cluster.

Limiting Behavior

Abstract We present a convenient way to obtain an optical power limiting behavior in a quantum dot molecule system, induced by an interdot tunneling. Also, the effect of system parameters on the limiting performance is investigated; interestingly, the tunneling rate can affect the limiting performance of the system so that the threshold of the limiting behavior can be a function of the input voltage, allowing the optimization of the limiting action. Furthermore, by investigating the absorption of the probe field, it is demonstrated that the optical limiting is due to a reverse saturable absorption mechanism; indeed, analytical results show that this mechanism is based on a cross-Kerr optical nonlinearity induced by the tunneling. Additionally, the limiting properties of the system are studied by using a Z-scan technique.

Optical Power Limiting

We report experimental results on a tin phthalocyanine: the nanosecond transient spectroscopy shows a reverse saturable absorption between 490–530 nm and 550–700 nm and the nonlinear transmission provides a better optical power limiting efficiency from 570 nm to 700 nm compared to C 60. This molecule is then combined in a tandem filter with a multiphoton absorber and a mixture of reverse saturable absorbers to achieve neutral-color broadband protection against ns pulses: the transmitted energy is clamped below 2 μ J throughout the visible.
