A fiber optic ammonia sensor using a universal pH indicator
Rodríguez Rodríguez, Adolfo Josué; Ruiz Zamarreño, Carlos
; Matías Maestro, Ignacio ; Arregui San Martín, Francisco Javier ; Cruz, René; May Arrioja, Daniel A. (MDPI, 2014)
Artículo / Artikulua 
A universal pH indicator is used to fabricate a fiber optic ammonia sensor. The advantage of this pH indicator is that it exhibits sensitivity to ammonia over a broad wavelength range. This provides a differential response, ... -
Gasohol quality control for real time applications by means of a multimode interference fiber sensor
Rodríguez Rodríguez, Adolfo Josué; Baldovino Pantaleón, Oscar; Cruz, René; Ruiz Zamarreño, Carlos ; Matías Maestro, Ignacio ; May Arrioja, Daniel A. (MDPI, 2014)
Artículo / Artikulua
In this work we demonstrate efficient quality control of a variety of gasoline and ethanol (gasohol) blends using a multimode interference (MMI) fiber sensor. The operational principle relies on the fact that the addition ... -
Low cutoff wavelength etched SMS structures towards verification of the quality of automotive antifreeze
Rodríguez Rodríguez, Wenceslao Eduardo; Rodríguez Rodríguez, Adolfo Josué; Ruiz Zamarreño, Carlos ; Del Villar, Ignacio ; Zúñiga Alanís, Manuel (IEEE, 2020)
Artículo / Artikulua
Optical fiber single mode-multimode-single mode (SMS) structures can be used as wavelength detection-based sensors. In this work, we focus on the performance at short wavelengths, where optical sources and detectors are ... -
Optical fiber sensors based on nanostructured materials for environmental applications
(2014) Tesis doctoral / Doktoretza tesia
La contaminación ambiental es la presencia de agentes físicos, químicos o biológicos presentes en el agua, suelo y aire; siendo perjudiciales para la salud de las personas, así como para la vida vegetal y animal. Las ... -
Sensitivity enhancement experimental demonstration using a low cutoff wavelength SMS modified structure coated with a pH sensitive film
Rodríguez Rodríguez, Wenceslao Eduardo; Del Villar, Ignacio ; Ruiz Zamarreño, Carlos ; Matías Maestro, Ignacio ; Arregui San Martín, Francisco Javier ; Rodríguez Rodríguez, Adolfo Josué; Domínguez Cruz, René (Elsevier, 2018)
Artículo / Artikulua
The multimode interference (MMI) effect in a single mode-multimode-single mode (SMS) can be used fordevelopment of wavelength shift detection based sensors. In this work, the focus is centered on obtainingwavelength shifts ...
