“…The sprayed solution spread around the target position where we want to deposit CNTs. After the proposal, direct synthesis method (Yamashita et al, 2004) and polymer embedding method (Sakakibara et al, 2005) have been reported. Though embedding CNTs into polymer materials have been already demonstrated (Sakakibara et al, 2003), the report was the first application to the passive mode-locker in the fiber-end-type configuration.…”

“…Since CNTs are nano-sized material, one of the largest problems to realize CNT-based devices is handling issue. Optical deposition method has an advantage in efficiency over the other handling methods, such as spraying (Set et al, 2004a;Set et al, 2004b), direct synthesis (Yamashita et al, 2004), and polymer embedding methods (Sakakibara et al, 2005). These methods mostly require complicated processes, large-scale setups, and dissipate significant numbers of CNTs.…”

“…Depending on the chirality of SWNTs, they can be either metallic or semiconducting, the latter being the desired behavior for nonlinear optical performance. Many optical applications could benefit from using SWNTs as nonlinear materials, such as noise suppression, wavelength conversion, and passive mode-locking [1][2][3]. A challenge when designing SWNT-based devices is incorporating the nanotubes in such a way as to enhance their interaction with light.…”

Linear and nonlinear optical properties of carbon nanotube-coated single-mode optical fiber gratings

et al. 2011

Single-wall carbon nanotube deposition on the cladding of optical fibers has been carried out to fabricate an all-fiber nonlinear device. Two different nanotube deposition techniques were studied. The first consisted of repeatedly immersing the optical fiber into a nanotube supension, increasing the thickness of the coating in each step. The second deposition involved wrapping a thin film of nanotubes around the optical fiber. For both cases, interaction of transmitted light through the fiber core with the external coating was assisted by the cladding mode resonances of a tilted fiber Bragg grating. Ultrafast nonlinear effects of the nanotube-coated fiber were measured by means of a pump-probe pulses experiment. © 2011 OCIS codes: 060.3735, 060.4370, 160.4236.Single-wall carbon nanotubes (SWNTs) have found innovative applications in the optical field due to their nonlinear properties in the near IR. Depending on the chirality of SWNTs, they can be either metallic or semiconducting, the latter being the desired behavior for nonlinear optical performance. Many optical applications could benefit from using SWNTs as nonlinear materials, such as noise suppression, wavelength conversion, and passive mode-locking [1][2][3]. A challenge when designing SWNT-based devices is incorporating the nanotubes in such a way as to enhance their interaction with light. One common method involves dispersing SWNTs in a solvent and spraying the solvent onto substrates in order to produce a nanotube film in the middle of a light beam [3]. Some inherent drawbacks in these configurations are the need for alignment and focusing stages, low SWNT burn thresholds, and low nonlinear interaction length. Solutions that overcome these challenges are based on SWNT deposition onto optical fibers. Tapered, D-shaped, and hollow optical fibers have been proposed to take advantage of the evanescent field interaction with SWNTs, distributing that interaction along the fiber length [4-6]. Nevertheless, manufacturing and handling these kinds of fibers is quite complex and delicate. In this work we propose for the first time SWNT deposition on standard optical fiber cladding for nonlinear applications. Interaction of light propagating through the fiber core with the outer SWNT coating is achieved via cladding mode resonances in a tilted fiber Bragg grating (TFBG). Two nanotube deposition methods have been carried out: dip-coating of the optical fiber in a SWNT suspension and wrapping of a SWNT film around the optical fiber. A TFBG is a kind of grating in which the index modulation planes are not orthogonal to the fiber axis but form a particular tilt angle. This inclination enhances the coupling of light from core mode to counterpropagating cladding mode resonances. Consequently, the grating transmission response is a multinotch response consisting of numerous cladding mode resonances in addition to the core mode resonance [see Fig. 1(a)]. The transverse mode profile of cladding modes spreads to the cladding of the fiber and interacts with the outer mediu...

“…The Bragg wavelength is directly proportional to the grating period, so great flexibility in setting the wavelength emission of a DFB laser is accomplished when writing Bragg gratings. The most widespread methods to inscribe Bragg gratings in optical fibers are the two-beam interferometric method [44] and the phase mask method [45,46], both based on the irradiation of periodic patterns of UV light upon photosensitive fibers.…”

“…CNT-based absorbers can be fabricated to operate both in transmission or reflection, which allows the use of either ring or linear cavity configuration [31]. Integration of nanotubes in optical cavities has been approached with different techniques, such as free-space [31,46], fiber-end [47], waveguide [48], and fiber structures [49][50][51].…”

AgradecimientosLa realización de una tesis doctoral no es un trabajo de carácter individual, sino el fruto de numerosas colaboraciones con compañeros y colegas que hacen posible obtener resultados de calidad, y esta tesis no es una excepción. Sin la ayuda de estas personas, no sólo en elámbito profesional sino en el emocional, habría sido imposible completar este trabajo de tesis. En esta parte del documento me gustaría transmitir mi agradecimiento a todos ellos.En primer lugar quiero mostrar mi más profundo agradecimiento a mis directores de tesis. Gracias a Javier Martí por ofrecerme la oportunidad de formar parte del Centro de Tecnología Nanofotónica, donde he podido desarrollar una excelente carrera investigadora durante losúltimos cinco años. Siempre ha mostrado un apoyo y confianza constante en mi labor que nunca olvidaré. Gracias a Pere Pérez por tomar la codirección de mi tesis en una etapa delicada de la misma. Toda la dedicación, consejos y confianza que ha depositado en mí han sido inestimables para sacar adelante esta tesis doctoral. Pero más allá del trabajo de investigación realizado está la amistad que se ha forjado durante estos años. Espero que nuestras colaboraciones se extiendan muchos años más en el futuro.Durante los años transcurridos en el Centro de Tecnología Nanofotónica he tenido la suerte de entablar amistad con fantásticos compañeros de trabajo. Necesariamente mi lista de agradecimientos la encabeza José Vicente Galán. Gracias a su consejo me incorporé a este instituto, y constantemente me ha echado una mano cuando lo he necesitado. Cómo no agradecer la compañía de Jesús Palací y Jordi Peiró, que han inundado de almuerzacos, desafíos y carcajadas el día a día de trabajo.
