Abstract:
1. An optical connector, comprising: a substrate; a light emitter positioned on the substrate; a case positioned on the substrate and covering the light emitter, the case comprising a first surface, a second surface, and a third surface, the second surface facing the light emitter and opposing the first surface, the third surface perpendicularly connecting the first surface to the second surface, the case comprising a first lens formed on the second surface and aligned with the light emitter, the case defining a first slot, a second slot, and a groove in the first surface, all of the first slot, the second slot, and the groove extending along a direction that is parallel with the third surface, the second slot and the groove being positioned at two sides of the first slot, the first slot forming a first total internal reflection (TIR) surface and a second TIR surface both facing toward the light emitter, the second slot forming a third TIR surface, the groove running through the third surface and forming a side surface parallel with the third surface, the case comprising a second lens formed on the side surface and optically aligned with the first lens through the first TIR surface; an optical fiber positioned in the groove and optically aligned with the second lens; and a photo detector positioned on the substrate, the photo detector being optically aligned with and optically coupled with the light emitter through the third TIR surface, the second TIR surface, and the first lens; wherein when the light emitter emits a light beam, the light beam is converged by the first lens to the first slot, and then split by the first TIR surface and the second TIR surface into two parts, a major part of the light beam is reflected by the first TIR surface to the second lens and the optical fiber for transmitting data, and a minor part of the light beam is reflected by the second TIR surface and then reflected by the third TIR surface to the photo detector.
