PURPOSE: An optical receiver module using an out-coupler is provided to improve the coupling efficiency by transferring most optical signal transmitted from a core to an optical receiver chip. CONSTITUTION: An optical fiber(500) is comprised of a core(501) and a cladding(502) surrounded by the outer block of the core(501). An optical signal is transmitted to the core(501). The cladding(502) located at the end is eliminated to expose the core(501). An optical receiver chip(510) is installed on an upper portion of the optical fiber(500) in order to receive the optical signal transmitted from the core(501). An optical fiber supporting unit(530) fixes the optical fiber(500). An out-coupler(520) is installed on the optical fiber supporting unit(530) and provided with plural lattices(522) between the core(501) and the optical receiver chip(510). The exposed core(501) is inserted into the out coupler(520).
