LASER MODULE WITH EXTERNAL CAVITY AND OPTICAL FIBRE REFLECTOR |
摘要 |
A laser module comprises a Fabry-Perot cavity active element with a facet bearing an anti-reflection coating and an external cavity made by an optical fibre Bragg grating with low reflectivity. This grating presents a non-uniform profile of modulation of the refractive index, asymmetrical in the direction of the grating length, such as to give rise to a position of the equivalent mirror plane that is offset towards the end of the grating that is closer to the active element.
