Abstract

En laserdiode (1) drives av en første integrerende forsterker (5) som mottar en likestrøms-referansespenning, Vre„ inngangsdata og negativ tilbakekopling fra en fotodiode (2) for en bak-fasett, og av en andre, bredbåndet forsterker (11) som mottar dataene og den negative tilbake-koplingen.
