SEMINAR: "PHYSICS IN An ENTORN QUOTIDIÀ"

 

 

 

 

Given by: Rafael García Molina

Date and hour: Wednesday, 4 October 2017

Place: Living room of Degrees: Rector Ramón Martín Mateo of the Faculty of Right

 

Abstract:

La física és una ciència que ens permet entendre com funciona el món, des de l'escala del macrocosmos (astrofísica, cosmologia...) fins a la del micromón (estructura atòmica i molecular, matèria condensada...). De fet, aquests dos escenaris són els que més fascinen a les persones que s'interessen per la física. Aquests dos meravellosos marcs representen escales extremes de temps, espai, energia... Però entre aquestes situacions extremes, la riquesa i potència de la física també es manifesta en multitud de fenòmens de la nostra vida quotidiana.

En aquesta conferència presentaré un conjunt d'experiments de física que es poden realitzar amb materials que trobem fàcilment al nostre entorn. La selecció d'experiments s'ha fet tenint en compte que són vistosos, divertits (ja que als físics també ens agrada passar-ho bé!) i, allò que és més important, perquè per a la seua correcta interpretació cal aplicar conceptes i formalismes de diferents àrees de la física. El grau de complexitat requerit per a explicar alguns dels experiments que es presentaran involucra des de coneixements bàsics de física fins a l'ús de models i formalismes sofisticats i elaborats.

SEMINAR: "SELF-ASSEMBLED CONJUGATED ORGANIC/POLYMER MICROCAVITIES FOR OPTICAL RESONATORS AND LASERS"

 

 

 

Given by: Yohei Yamamoto

Date and hour: Friday, 22 September 2017 to the 11:30 hours

Place: Polyvalent Room of the Department of Physics Applied. Faculty of Sciences, Phase II

 

Abstract:

Optical microcavities play an important role for the next-generation light technology. Recently, we succeeded in fabricating spherical microcavities from %u03C0-conjugated polymers (CPs) by simple self-assembly process. We found that the microcavities exhibit whispering gallery mode (WGM) resonant photoluminescence (PL) upon focused laser excitation, where PL generated inside the sphere is confined via total internal reflection at the polymer/air interface.[2%u20138] The resonance occurs when the wavelength of the light is an integer multiple of the circumference of the microsphere. The CP-based microcavities have benefits to the conventional microcavities in the following points:

(1) Simple and low-energy fabrication process to obtain well-defined microspheres.

(2) The microcavities act ace both cavity and emitter.

(3) The microcavities possess high refractive index and photoabsorptivity.

(4) Potent use for electrically-driven WGM and laser oscillation.

In this presentation, recent results on the fundamentals of the self-assembly of the CPs, resonant PL from the CP microspheres, intra- and intersphere light energy conversion, , optically-pumped lasing, and the future prospects to realize light-, electrically-, and chemically-driven WGM and lasing will be presented.
