dcterms:description
PM optical fiber with a PM single mode couplers or splitters at each fiber end can be used as a sensitive structure for fiber sensing applications. The sensitive structure is created with two lasers at λ = 1550 nm. Each laser is connected to the opposite sides of two the single mode PM couplers with PM fiber connecting both PM couplers. One DFB laser is isolated and its light goes through variable attenuator. Isolation is necessary for DFB laser stability. The second laser is F-P laser without any isolator. Its radiation is driven as with driven current so with DFB laser passing through SM optical fiber. Small changes of DFB laser light spectrum passing through PM optical fiber activate large changes in FP laser radiation spectra. DFB laser is tunable with temperature and its radiation is a stimulated light for FP laser. If the power of DFB laser is above threshold power, FP laser losses its multimode behavior. Threshold powers, tunable range of DFB laser, changes in mode structures of FP laser will be presented together with application possibilities of coupled laser diodes system.
