At the same time the EDF be used to amplify the signal in a fiber ring laser system. There are a bandwidth filters and an electro-optical modulator be used to study the effects of fiber ring laser mode -locking characteristic. Then we change the characteristic of the system to double ring. The upside and the underside of the ring have EDFA as the source of amplifier. We comparing the same lengh with modulated frequency at 3.044MHz and 12.288MHz, and the different lengh with modulated frequency at 12.2879 MHz. Measure the optcal power and peak to peak of the time trace and the analysis of output result and its characteristics. We have two result, one is linear and the other one has threshold currnet. We can get the result what we want by controling the pumping power. We use the linear result in communicated applications, then the threshold currnet can use to control the other ring output power, to achieve optical switch.
