[ES] Este trabajo demuestra el empleo de redes de difracción de Bragg superestructuradas (SSFBG) como codificadores/decodificadores con respuesta espectral rectangular en sistemas coherentes de secuencia directa OCDMA sobre ...
[EN] We demonstrate a chirped microstructured polymer fiber Bragg grating based on taper technology for strain sensing application. The effective bandwidth of the grating is dependent on strain and remains practically ...
[EN] We demonstrate a simple way to fabricate phase-shifted fiber Bragg grating in polymer optical fibers as a narrowband transmission filter for a variety of applications at telecom wavelengths. The filters have been ...
