“…However, due to the exceptionally low optical loss of silica, it is possible to fabricate devices allowing optical field amplification without damaging the material, allowing nonlinear behaviors to be excited [83][84][85][86][87][88][89][90][91][92][93]. In addition, the ease of doping the amorphous silica matrix provides a complementary route to designing and realizing nonlinear devices from silica [18,77,84,[94][95][96][97][98][99]. Silicon nitride is a popular wide bandgap dielectric material that has been the focus of numerous research efforts.…”

AbstractAlthough the first lasers invented operated in the visible, the first on-chip devices were optimized for near-infrared (IR) performance driven by demand in telecommunications. However, as the applications of integrated photonics has broadened, the wavelength demand has as well, and we are now returning to the visible (Vis) and pushing into the ultraviolet (UV). This shift has required innovations in device design and in materials as well as leveraging nonlinear behavior to reach these wavelengths. This review discusses the key nonlinear phenomena that can be used as well as presents several emerging material systems and devices that have reached the UV–Vis wavelength range.

“…In addition, flexible polymers have an outstanding function to self-assemble into optical micro-cavities with high-quality, where propagated light beam will be continuously confined via total internal reflection. Consequently, the large evanescent field around the air-cavity interface results in efficient conversion between photon and surface plasmon [70]. Herein, we describe a plasmonic conversion to obtain sub-wavelength output of full-color lasers in a silver-polymer heterostructure [71].…”

Surface plasmons are coherent electron oscillations behaving as localized and propagated modes in metal nanoparticles and nanowires, respectively. In this chapter, we first review some of the applications made in plasmonics with gold nanorods/nanospheres and silver nanowires. For gold nanoparticles with a size of 1-100 nm, the surface plasmons are confined around the particle surface as localized modes to enhance the near-field. For diameter of around 200-300 nm silver nanowires with a length up to 10 μm, the surface plasmons can propagate along the nanowires as waveguide modes to guide the plasmons. We then describe some novel results with regarding to gold nanorod enhanced light emission, silver nanowire supported plasmonic waveguide, gold nanosphere mediated whispering-gallery-mode emission, and energy conversion in silver-polymer plasmonic nanostructures. The work of this chapter highlights the applications of metal nanoparticles and nanowires in plasmonic waveguides to achieve optical energy generation, propagation, and conversion.

“…es posible sintetizar nanoestructuras tan simples como esferas, o, complejas, como nanotubos, nanopirámides, entre otras más. La importancia en el control de la forma y el tamaño radica en las nuevas oportunidades tecnológicas que re-presentan, por ejemplo, en el desarrollo de nanoantenas, aplicaciones en microláseres, aplicaciones en celdas solares y nuevas oportunidades espectroscópicas como SERS (Castro-Beltrán et al, 2017;Shi et al, 2013). Para el caso particular de estudios basados en SERS, la forma de las NPs, su tamaño y su capacidad bioquímica superficial para contener (adsorber) compuestos orgánicos en su superficie es fundamental, así como el realce del campo eléctrico en su superficie (Yingcheng et al, 2015;Yang et al, 2014).…”

En este trabajo presentamos la fabricación de nanopartículas de plata (Ag-NPs) por medio de ablación láser (AL) en medio acuoso, y su aplicación como elementos de realce de señales Raman a través de procesos tipo SERS. Esta metodología permite obtener suspensiones estables de NPs libres del uso de procesos químicos, con dispersiones de tamaños relativamente pequeñas y de fácil procesamiento para la implementación de sustratos SERS de sílice. A través del uso de alícuotas a diferentes concentraciones de Rodamina 6G (R6G), se demuestra que con estas Ag-NPs se alcanzan umbrales de detección de señal Raman en concentraciones del orden de nM. El estudio de la distribución de las Ag-NPs sobre un sustrato de sílice se llevó a cabo por microscopía de fuerza atómica (AFM). A su vez, se presentan algunos resultados de simulación de la magnitud de los campos generando hot spot en regiones específicas de las Ag-NPs tomando en cuenta la morfología de algunos de los aglomerados identificados por microscopía de barrido electrónico (SEM) en los sustratos SERS. En comparación con algunos reportes previos, el presente trabajo demuestra bajo umbral de detección e implementación sencilla en sustratos SERS.
