Abstract

The invention concerns a gallery mode microdisc system for an electrically pumped optical source, the microdisc (1) being formed on one face of a substrate (2), the lower part of the microdisc being provided with an electrical contact referred to as the lower contact (4), the upper part of the microdisc being provided with an electrical contact referred to as the upper contact (6), the upper part of the microdisc being covered with a protective layer (3) of electrically insulating material, the central part (5) of the microdisc being electrically neutralized in order to prevent the passage of an electric current in said central part.
