A chip-scale electrical soliton modelocked oscillator

Abstract

This paper introduces a chip-scale electrical soliton modelocked oscillator, which self-generates a periodic train of electrical soliton pulses. This circuit is made possible by combining a nonlinear transmission line (NLTL) with a unique amplifier that tames the instability-prone soliton dynamics in a closed-loop NLTL. This chip-scale prototype produces a pulse width of 293ps and demonstrates the feasibility for future widths close to 1ps, adding a new direction in pulse-based electronics
