Dual-band wavelength-swept active mode locking laser for multi-band fiber-optic sensors

摘要

This paper shows experimentally dual wavelength swept at multi band (O,C-Band) property with active mode locking (AML) method. Unlike conventional wavelength swept laser, AML wavelength swept laser does not require any wavelength selecting filter in the cavity. The cavity has two free spectral ranges (FSRs) depend on dual path configuration. This wavelength swept laser can be useful for wide-band fiber-optic application such as Optical Coherence Tomography and Fiber Bragg Grating sensor system.
