摘要： A laser module (1) comprises a Fabry-Perot cavity active element (2) with a facet (3) bearing an anti-reflection coating and an external cavity made by an optical fibre Bragg grating (5) with low reflectivity. This grating (5) 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 (5) that is closer to the active element (2).

P is not equal to zero for the plurality of trenches (24) along the grid (18), wherein the coupling parameter
P of a trench (24) is defined by the formula (I), wherein d
res is a distance of the trench (24) to the active layer (10),
w is a width of the trench (24) and Δ
n is the refractive index difference between a refractive index of the trench (24) and a refractive index of a material surrounding the trench (24). The invention in particular relates to a laser diode in which a distributed feedback occurs over a surface grid of high order while radiation is decoupled on one side and in which the coupling strength of the grid is matched to the power density of the wave guided in the laser diode.

摘要： A laser heterostructure (10) having an active layer, a lateral waveguide terminating in an output aperture (11), and a gain section (17) with a current drive electrode. A rear surface distributed Bragg grating (12) with a tuning current electrode (19) is formed on a surface of said laser heterostructure. The laser also includes a front surface distributed Bragg grating (14) with a tuning current electrode (16) on a surface of the laser heterostructure. The front surface distributed Bragg grating is closer to the output aperture than the rear surface distributed Bragg grating. There is a space (15) between the rear surface distributed Bragg grating and the front surface distributed Bragg grating. A current drive electrode (18) is formed on the space. Operation is best when the front surface distributed Bragg grating has adequate reflectivity at the Bragg wavelength with minimal scattering loss at other wavelengths, particularly at the wavelength of the rear surface Bragg grating.
