Paper Abstract

We present a device which has potential for use as a fiber sensor. The device is formed by leading two of the output ports of a 3 X 3 optical fiber flat fused coupler back to two of the input ports to form a double ring resonator structure. A 3 X 3 flat fused coupler with coupling coefficient Kl equals 0.173 II and an excess loss of about 1 dB was fabricated. The double ring resonator was formed as described. By modulating one ring with Pz element, the finsse of the device was approximately 36. Therefore; the two rings may provide one ring as a reference arm and the other ring as a sensing arm. Thus the device may have potential for use as a sensitive optic fiber sensor.
