Diffraction grating-based demultiplexers for SI-POF networks

The proceeding at: 22nd International Conference on Plastic Optical Fibers (POF 2013), took place in 2013 September,11-13, in Armação dos Buzios, Rio de Janeiro, (Brasil). The event Web site at: http://www.pof2013.org.br/ .In this paper, the possibility of implementing low-loss demultiplexer devices based on diffractive elements for SI-POF networks is studied. Theoretical and experimental analyses of three different diffractive setups are reported. It is also presented a 3-channel demultiplexer proposal, based on a transmission diffraction grating, with experimental insertion loss from 3.6dB to 5.8dB and adjacent channel crosstalk from −16.4dB to −28.6dB. This proposal presents low losses and low crosstalk, and it is very easy to implement in a compact reflective setup.This work has been sponsored by Ministerio de Economia y Competitividad (TEC2012-37983-C03-02) and Ministerio de Educacion, Cultura y Deportes (PRX12/00007),Publicad
