Claim 0:
1. An optical probe package structure, applicable to a test environment for testing a plurality of optical chips on a wafer, comprising:
a main body;
a plurality of optical fibers, coupled to the main body, the optical fibers being arranged on a substrate, and each of the optical fibers being used to transmit an optical signal along a first direction;
an optical fiber positioning area, disposed on the main body, and the optical fiber positioning area having a plurality of V-grooves, each of the V-grooves accommodating one of the optical fibers, and the optical fibers being positioned by the V-grooves;
a mode field conversion waveguide structure, disposed on the main body and coupled to the optical fibers, the mode field conversion waveguide structure being used for receiving the optical signal in each of the optical fibers and converting a mode field diameter of the optical signal, and the mode field conversion waveguide structure having an incident end, from which the optical signal transmitted by each of the optical fibers entering the mode field conversion waveguide structure; and
an optical waveguide, disposed on the main body and coupled to the mode field conversion waveguide structure, the optical waveguide having an emitting end, and the emitting end being provided with a facet, and the facet having a facet angle;
wherein, the facet angle causes the optical signal after mode field conversion by the mode field conversion waveguide structure to be totally reflected by the facet to generate a reflected optical signal transmitted from the emitting end of the optical waveguide along a second direction, and the reflected optical signal enters one of the optical chips.
