This set-up has been used to write 1 dimension diffraction grating at the fiber end-face. Its far field intensity distribution has been measured and compared with simulations assuming rectangular air hole structure of same width and period. By comparing diffraction efficiencies, a first attempt of measuring hole deep is achieved.}, organization = {This work has been supported by the projects TEC2013-47264-C2-1-R, TEC2016-76021-C2-2-R (AEI/FEDER, UE) financed with FEDER funds, and grant BES-2014-069736 of the Spanish government and by the Parliament of Cantabria postdoc grant.}, publisher = {Asociación Científica de Óptica y Fotónica de Santiago }, publisher = {10ª Reunión Española de Optoelectrónica, OPTOEL’17, 2017, Santiago de Compostela, p. 122-125}, title = {Femtosecond laser inscription of diffractive element in optical fiber end-face}, author = {Pallarés Aldeiturriaga, David and Rodríguez Cobo, Luis and Ruiz Lombera, Rubén and Quintela Incera, Antonio and López Higuera, José Miguel}, }
