This work presents a novel lensed plastic optical fiber (POF), efficiently coupled with a light source. A convexo-concave plastic lens (CCPL) was bound to a flat-end plastic optical fiber using laser transmission welding (LTW) to form a convexo-concave-shaped fiber endface (CCSFE). The novel lensed plastic optical fiber has a longer working distance and a higher coupling efficiency than conventional lensed plastic optical fibers. 850 nm fiber is often used in high-power 2.5 Gb/s transmission rate. Experimental POF is perfluorinated POF, 62.5–500 μm diameter, 850∼1300 μm wavelength, 10 dB/km power loss rate, 2.5 Gb/s transmission rate. Because of the small diameter of POF, it is difficult to couple between the light source and POF. Therefore, it is important to develop a lensed fiber structure to increase the coupling efficiency. Experiments indicate that the coupling efficiency between a laser diode at a wavelength of 850 nm and a graded-index POF is as high as 85% with a long working distance of 250 μm. The measured tolerance, in relation to the lateral and vertical displacements and tilt, are satisfactory for practical active alignment.

The explosive growth in the use of the Internet and multimedia applications in both the home and the office has fueled the requirement for high-bandwidth communication systems capable of processing huge volumes of data in a prompt and reliable manner. Plastic optical fiber (POF) has emerged as an ideal solution for meeting this requirement and is now specified by many architects as a simple, one-cable solution for home and office data communication networks. This study presents a modified flip-chip light emitting diode (LED) package for use in short-distance, POF-based communication systems. In contrast to the planar surface of the traditional design, the proposed LED package has a curved boundary surface between the underfill and the air. This boundary surface functions as a virtual lens, which focuses the light emitted by the LED into the acceptance cone of the optical fiber such that the amount of light coupled into the fiber core is maximized. The proposed design yields an average coupling efficiency of around 49.6% over an LED-optical core misalignment range of 0.4–3 mm. Furthermore, the curved boundary surface reduces the distance between the emitting source and the ambient environment; therefore, it improves the thermal dispersion efficiency of the LED package.
