1. An optoelectronic module, comprising:
a substrate;
a covering member disposed on the substrate, the covering member comprising an upper cover portion, a peripheral sidewall portion connected to the upper cover portion, and an inside partition extending from the upper cover portion to the substrate and delimiting a first cavity and a second cavity, wherein the first cavity is separated from the second cavity;
a light emitting element, disposed on the substrate as corresponding to the first cavity; and
a light receiving element, disposed on the substrate as corresponding to the second cavity;
wherein the inside partition has a first inner wall surface located in the first cavity and a second inner wall surface located in the second cavity; and
wherein a first protruded-recessed structure is formed on the first inner wall surface and the first protruded-recessed structure is a periodic protruded and recessed structure.
