Acoustic levitation has become a crucial technique for contactless manipulation in several fields, particularly in biological applications. However, its application in the photonics field remains largely unexplored. In this study, we implement an affordable and innovative phased-array levitator that enables stable trapping in the air of micrometer...

In this work, we demonstrate the properties of Rhodamine B-doped polymeric cylindrical microlasers to perform either as gain amplification devices through amplified spontaneous emission (ASE) or as optical lasing gain devices. A study based on different %wt concentrations of microcavity families with distinct geometrical features demonstrates the c...

We report on experiments with Möbius strip microlasers, which were fabricated with high optical quality by direct laser writing. A Möbius strip, i.e., a band with a half twist, exhibits the fascinating property that it has a single nonorientable surface and a single boundary. We provide evidence that, in contrast to conventional ring or disk resona...

Polymeric cylindrical micro-pedestals were fabricated using a low-cost direct laser writing system. These were coated with Rhodamine 6G dye to allow lasing action. Microlasers, exhibit Whispering Gallery Modes with Q ≥ 2000 and a lasing threshold ≤ 5 µJcm – ² .

Our current work exploits direct laser writing (DLW) and low one-photon absorption (LOPA) in a low-cost three-dimensional optical fabrication system designed to print micrometric polymeric structures. Micropedestals were obtained by focusing a laser beam on a photoresist layer deposited on a silica glass substrate. Subsequent coating with rhodamine...

We report on experiments with M\"obius strip microlasers which were fabricated with high optical quality by direct laser writing. A M\"obius strip looks like a ring with a twist and exhibits the fascinating property that it has only one boundary and a one-sided nonorientable surface. Hence, in contrast to conventional ring or disk resonators, a M\"...

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 rela...
