Shot Noise Limit

To optimize the performance of a laser-based polarimeter, a mathematical simulation was performed. High-modulation currents allow a corresponding increase in signal. However, the effect of ohmic heating puts an upper limit on the power input to the solenoid. With this constraint, one can systematically choose the wire diameter and the number of turns per unit length. An experimental verification of the optimized parameters provided performance approaching the shot-noise limit. By using higher modulation currents, one can operate at 1 kHz to achieve detectability in the microdegree range, without the complications of high-frequency (100 kHz) modulation.

High Frequency Performance

In this study, we aimed to improve the VOA-based simple chaotic circuit proposed by Sprott in the literature by using FTFN-based circuit topology. And also, by choosing one of the FTFN-based circuits whose chaotic dynamics are very similar to that of Chua's circuit as a reference model, we tested the performance of this model at different frequencies and its extended frequency performance has been verified by laboratory experiments and PSpice simulations.
