description: Our study deals with the spectral stabilization of laser diodes by external cavities incorporating a resonant grating filter. The first part of this work concerns the theoretical study of the external cavity and the criteria required for the characteristics of the filter to obtain a monomode emission. The conception and the realization of the different gratings, used in Littrow-like configuration, enable us to stabilize conventional laser diodes with a SMSR above 30dB, though being very sensitive to misalignments due to low angular tolerance of these filters. The second part concerns new types of filters, whose resonant grating is surrounded by two lateral reflectors with half-period. These filters have a wide angular tolerance close to 10°, combined with a nanometric bandwidth, that authorizes a cat's eye configuration, compact and easy to get working, all the while obtaining a spectral stabilization with a SMSR above 30dB.
