Paper Abstract

It is well known that 3 X 3 optical fiber coupler can take two general types of configurations one of them is a triangular structure and other is a flat form. This kind of structure can be fabricated by placing three fibers side by side. The three fibers are fused and pulled from both sides through the translation in opposite directions of two movable platforms, to which the fibers are secured. We present a device has potential for use as a dense wavelength division multiplexing/demultiplexing but which uses only one coupler. Leading back one of the output port to the same input port forms this device. A 3 X 3 optical fiber flat fused coupler with coupling coefficient Kl of about 35 degree and an excess los and loop loss of about 1 dB was fabricated. The video channel of 6 MHz spacing and separation between channels of about 3 MHz was generated by modulating the loop length 34 meters with PZ element. The extinction ration was about 30 dB. Thus the device may have a potential for use as WDM/WDD.
