A new type of novel all-fiber power splitter has been designed and experimentally demonstrated, which could be directly applied to very short reach (VSR) passive optical networks (PON) based on hard polymer clad fibers (HPCF). Overcoming silica glass manufacturing difficulties, we successfully developed a 4×4 HPCF star coupler using a micro hydrogen-burner flame brushing. The device showed an excellent uniformity in power splitting ratio along with a very low excess loss of 4.58dB and insertion loss of 10.5dB over a wide wavelength range 600-900nm. Transmission quality and power budget for PON using the devices were analyzed for 1.25 and 2.5Gbps at 10, 25, 50m, whose results confirmed highly practical potential of the proposed device in VSR PON systems with a reasonable power budget.
