“…They can be used also as wavelength selector in the diode gain bandwidth. The same chip can then be used for all the wavelengths and the cost can be decreased [45]. The use of "comb" filters, such as described in [46], is also of high interest for multi-wavelength or tunable sources.…”

Isabe1le. Riant(a,alcatelfi The impressing growth of Wavelength Division Multiplexing (WDM) transmissions has pushed the development of photo-induced Bragg gratings in optical fibers. Numerous studies on the photosensitivity of germanosilicate fibers have then been carried out since its discovery in 1978, to understand, stabilize and enhance the effect. Some of those studies are presented here together with some illustrating applications.

Bragg gratings photoimprinted in optical fibers have become essential for flattening the gain of amplifiers, stabilizing the wavelength of pumps or sources, and for fiber lasers. Advantages are low insertion loss, very low polarization sensitivity and an extremely flexible design. Those advantages make gratings also very attractive candidates for applications of complex filtering or precise chromatic dispersion compensation. This article briefly describes the different types of Bragg gratings as well as several examples of applications in optical telecommunications. To cite this article: I. Riant, C. R.

Résumé Les réseaux de Bragg photoinscrits dans les fibres optiques sont devenus indispensables pour l'égalisation du gain des amplificateurs, la stabilisation en longueur d'onde des pompes ou des sources, et pour les lasers à fibre. Leurs atouts majeurs sont de faibles pertes d'insertion, une très faible sensibilité à la polarisation et une conception extrêmement flexible. Ces atouts en font également des candidats très attractifs pour les applications de filtrage complexe ou de compensation de dispersion chromatique fine. Cet article décrit brièvement les différentes familles de réseaux de Bragg ainsi que quelques exemples d'applications dans les télécommunications optiques. Pour citer cet article : I. Riant, C. R.

“…Using a temperature-insensitive and low-chirp fiber Bragg grating reflector as the external cavity for the semiconductor gain element, fiber grating external cavity lasers (FGECLs) have been developed for 2.5 Gbit/s WDM with a low bit error rate penalty. [3][4][5][6] It has been shown that the side-mode suppression ratio (SMSR) of the non-ARcoated FGECL exhibits a current-dependent oscillation. 7,8) To avoid the formation of an intra cavity and increase the SMSR, Morton et al 9) have demonstrated an FGECL configuration by applying antireflection (AR) coatings to both the fiber tip and the diode laser front facet (facet closest to fiber tip).…”

The costs of remedial work, and the radon level reduction achieved, have been studied in a series of domestic properties in Northamptonshire, which is a radon affected area. The cost-effectiveness of the series is similar to published theoretical estimates for proposed national remediation programmes, and five times more effective than our similar analysis for the National Health Service workplace, if it is assumed that 100% of householders discovering levels above 300 Bq m −3 implement remediation. In practice, in the UK, far fewer of those who arrange an initial radon test proceed to remediation, but this domestic programme could be cost effective if more than 5% carry out remediation.Our series confirms that a considerable number of householders with radon levels in the 200 to 300 Bq m −3 range do not seek or implement remediation work.
