Variable Optical Attenuator with Integrated Control Based on Strongly Correlated Materials

 

Introduction

 

Accurate optical attenuation in optical network systems and optical devices is currently achieved through the use of expensive, complex and bulky external sensors in combination with a linear controller. 

 

Description of Technology

 

This technology is a variable optical attenuator that attenuates infrared wavelengths. This attenuator does not require external optical sensors because it is controlled by a closely correlated electrical sensing system. Attenuator materials are able to be adjustable by relating the electrical properties under various conditions to the optical transmission. The device adjusts quickly and accurately over a wide range of wavelengths.
