Wavelength switching in pump-diode-modulated mode-locked and Q-switched Er-fiber laser

Abstract
An Er‐doped fiber laser configuration is described which utilizes a coupled cavity terminated with Bragg reflectors with intracavity 1.48 μm laser diode used as pump source and modulator. This approach represents a minimal configuration for a mode‐locked and Q‐switched fully integrated fiber laser. Individual addressing of reflectors and fast wavelength switching can be obtained by current modulation of the laser diode in a dispersive compound resonator.
