Abstract

La présente invention concerne un module de moteur optique pour émettre et recevoir des signaux optiques servant à réaliser une communication optique. Un module de moteur optique pour une communication optique selon les modes de réalisation de la présente invention comprend : un élément optique pour recevoir ou émettre une lumière ; un élément électrique pour piloter l'élément optique ; et un substrat de séparation thermique comprenant des parties d'émission de chaleur formées séparément pour émettre respectivement de la chaleur pour l'élément optique et l'élément électrique, et une partie d'isolation disposée entre les parties d'émission de chaleur et bloquant la conduction de chaleur entre les parties d'émission de chaleur, l'élément optique et l'élément électrique étant disposés sur le même plan. En conséquence, l'élément optique et l'élément électrique sont séparés thermiquement, permettant à une communication à grande vitesse de 10G ou plus d'être mise en œuvre.
