Ultrafast pulsed laser evaluation of Single Event Transients in opto-couplers

TL;DR

This paper presents a new testing setup using a 1064 nm fiber laser to evaluate single event transients in optocouplers, demonstrating for the first time the occurrence of SETs in the 4N35 optocoupler.

Contribution

Introduction of a novel laser-based testing method for detecting SETs in optocouplers, enabling first-time observation of SETs in the 4N35 device.

Findings

SETs observed in 4N35 optocoupler

Development of a laser testing facility

First demonstration of SETs in this component

Abstract

We build a 1064 nm fiber laser system-based testing facility for emulating SETs in different electronics components and ICs. Using these facilities, we tested the 4N35 optocoupler to observe SETs for the first time.
