All-optical Switch Introduction

The all-optical switch is the main element in the optical communication network. As the key to realize all optical network, it has a low pumping power, high switch efficiency, fast response time characteristics, so much attention in recent years has been paid. From the late 1980s to the present, many research groups have conducted in-depth […]
