SANTOS-AGUILAR, Joe  y  GUTIERREZ-MARTINEZ, Celso. Photonic Filters Using Optical Retarders Based on Birefringent Optical Media. rev. cienc. [online]. 2015, vol.19, n.2, pp.93-98. ISSN 0121-1935.

Photonic f lters can be used for f ltering the spectrum of wide-band optical sources such as light emitting diodes (LED) or multimode laser diodes (MMLD). In this work the use of birefringent optical media such as polarization maintaining f ber (PMF) or birefringent optical waveguides on Lithium Niobate (LiNb03) crystal, perform as optical f lters. The birefringent optical media, used as optical retarders, modify the optical spectrum by "channelizing" them. These devices act as photonic f lters, thus modifying an optical spectrum. As reported in this paper, integrated optics photonic f lters are easily implemented by birefringent optical waveguides on LiNbO3 electrooptic crystals. The practical f ltering of LED and be used for MMLD spectra is demonstrated in this work. The photonic f lters can implementing microwave f lters or optoelectronic multiplexing for radio or radio over f ber schemes

Palabras clave : photonic f lters; optical delays; broadband optical sources; birefringent optical media.
