Tunable output power varying with the splitting ratio of a coupler from a fiber ring semiconductor laser.
The tunable output power characteristics of a fiber ring semiconductor laser have been studied by use of rate equations. An expression for the tunable output power is deduced. The analysis confirms that there is an optimum coupler splitting ratio to trade off between wavelength tuning width and output power.
