@article{10902/2173, year = {2013}, month = {4}, url = {http://hdl.handle.net/10902/2173}, abstract = {A narrow filtering technique based on the spectral overlapping of two uniform FBGs and applied to obtain a Single Longitudinal Mode (SLM) laser is proposed and demonstrated in this work. The two FBGs are spectrally detuned to reduce their coincident reflection response narrowing the equivalent filter bandwidth. A proof-of-concept linear laser has been built and tested exhibiting SLM operation even with temperature and strain variations.}, organization = {The authors are grateful to the Spanish government project TEC2010-20224-C02, to the Spanish Ministry of Education and Culture, and to the grant AP2009-1403.}, publisher = {The Optical Society (OSA)}, publisher = {Optics Express, 2013, 21(8), 10289–10294}, title = {Single-longitudinal mode laser structure based on a very narrow filtering technique}, author = {Rodríguez Cobo, Luis and Quintela Incera, María Ángeles and Rota Rodrigo, Sergio and López Amo, Manuel and López Higuera, José Miguel}, }
