摘要

This paper demonstrates a special stochastic operation mode of a photonic element with a thin GeTe film deposited at a silicon nitride waveguide. As opposed to traditional deterministic switching between stable states, it has been shown that identical pump laser pulses cause a stochastic change in the transmission coefficient. The discovered effect opens up new possibilities for constructing compact and energy-efficient entropy sources and stochastic computing units directly within integrated photonic circuits.
