KEYWORDS: Lithium, Light emitting diodes, Fiber Bragg gratings, Power supplies, Control systems, Fiber lasers, Semiconductor lasers, Wavelength tuning, LED displays, Voltage controlled current source
In this paper,we introduce a novel tunable external-cavity semiconductor laser that simultaneously achieves rapid tuning rate and tuning precision by mechanical control. A stepping motor is applied in the tuning system. By control of the angular displacement of stepping motor, we can modify the centre wavelength of FBG.
