New biconically tapered fiber star coupler fabricated by indirect heating method

Integration of Eco-Friendly POF Based Splitter and Optical Filter for Low-Cost WDM Network Solutions

“…Furthermore, comparing with Imoto (1987) works, this fabrication method are produce less harmful gases such as nitrogen, sulfur or Carbon monoxide as produced by reaction of burning process using oxyhydrogen burner. The change of original diameter of POF considerably led to the change on optical properties including numerical aperture and maximum acceptance angle.…”

“…Furthermore, the continuous processing capability leads us to the reduction in fabrication time and improved yield. This method is expected to drastically reduce coupler fabrication costs (Imoto, Maeda et al 1987). …”

“…Essentially, the term of 'fusion' defines the act or procedure of liquefying or melting by the application of heat (Imoto, Maeda et al 1987). In order to develop the economical POF splitter, this chapter is undertaken to modify the typical fusion technique, whereby the technique is fully implemented by handwork.…”

Power Analysis on Same Filter Different Sources for Selection of Spectral Filters in Optical Demultiplexer

“…For example, red light with 650 nm wavelength modulated with Ethernet signal while blue, green and yellow lights carry image information, Radio Frequency (RF) and television signal, respectively (Imoto et al, 1987). Conceptually, the same device can also perform the reverse process with the same WDM techniques, in which the data stream with multiple wavelengths decomposed into multiple single wavelength data streams.…”

Optimization of WDM-POF Network for In-Car Entertainment System

“…In addition, from the stand point of device design, the diameter of the fused tapered region, where stress is concentrated, is too small in conventional couplers. The structure causes a high incidence of fiber fracture, which results in poor reliability [9][10][11][12].…”
