Soliton Electronics and Biolab-on-Chip
Solitons: Are pulse-shape nonlinear waves that travel maintaining spatial localizations of energy in the pulse shape.This talk consists of two topics, that have been important research foci in my lab.
In the first part of this talk, I will present the first stable self-sustained electrical soliton oscillator that we have recently developed. The soliton oscillator consisting of a nonlinear transmission line (NLTL) and a nonlinear amplifier that "tames" the instability-prone dynamics of the NLTL self-starts by amplifying background noise to generate a stable soliton train in steady-state.
While the NLTL has been extensively exploited as a sharp soliton pulse generator in the past decades, this traditional approach utilizes the NLTL as a 2-port system that requires an external high-frequency input to generate the soliton output. Our soliton oscillator is a self-contained 1-port system that does not require any external high-frequency input in generation of the soliton train. The soliton oscillator, as a direct analogue of the optical soliton mode-locked system such as the soliton fiber ring laser, is expected to find a variety of applications in high-speed metrology.
