A switchable digital microfluidic droplet dye-laser.
Digital microfluidic devices allow the manipulation of droplets between two parallel electrodes. These electrodes can act as mirrors generating a micro-cavity, which can be exploited for a droplet dye-laser. Three representative laser-dyes with emission wavelengths spanning the whole visible spectrum are chosen to show the applicability of this concept. Sub-microlitre droplets of laser-dye solu...
متن کاملA multi-color fast-switching microfluidic droplet dye laser.
We describe a multi-color microfluidic dye laser operating in whispering gallery mode based on a train of alternating droplets containing solutions of different dyes; this laser is capable of switching the wavelength of its emission between 580 nm and 680 nm at frequencies up to 3.6 kHz-the fastest among all dye lasers reported; it has potential applications in on-chip spectroscopy and flow cyt...
متن کاملLevitated droplet dye laser.
We present the first observation, to our knowledge, of lasing from a levitated, dye droplet. The levitated droplets are created by computer controlled pico-liter dispensing into one of the nodes of a standing ultrasonic wave (100 kHz), where the droplet is trapped. The free hanging droplet forms a high quality optical resonator. Our 750 nL lasing droplets consist of Rhodamine 6G dissolved in et...
متن کاملA Nanoimprinted Microfluidic Dye Laser
We present a polymer based microfluidic dye laser suitable for integration into micro total analysis systems, fabricated by nanoimprint lithography (NIL) [1] in the thermoplastic polymer COC (cyclo olefin copolymer) [2]. The device (se figure 1 and 2) consists of microfluidic channels, with sizes ranging from several mm down to 16 μm, and optical waveguides, all fabricated in one single NIL ste...
متن کاملRapid droplet mixers for digital microfluidic systems.
The mixing of analytes and reagents for a biological or chemical lab-on-a-chip is an important, yet difficult, microfluidic operation. As volumes approach the sub-nanoliter regime, the mixing of liquids is hindered by laminar flow conditions. An electrowetting-based linear-array droplet mixer has previously been reported. However, fixed geometric parameters and the presence of flow reversibilit...
