Optofluidic dye lasers are microfabricated liquid dye lasers enabled by the microfluidics technology. The integration of dye lasers with microfluidics not only facilitates the implementation of complete ''lab-on-a-chip'' systems, but also allows the dynamical control of the laser properties which is not achievable with solid-state optical components. We review the recent demonstrations of onchip liquid dye lasers and some of the pre-microfluidics era microscopic dye lasers which are also amenable to microfluidic implementation. Potential applications and future directions are discussed.

“…And compared to solid state dye lasers, microfabricated liquid dye lasers don't suffer from the photobleaching problem because the dye solution can be continuously replaced. Several groups have demonstrated such on chip dye lasers using different materials and laser cavities [1,2,3]. Tunable output was also obtained using concentration or index tuning methods [3,4].…”

We demonstrated a continuously tunable optofluidic distributed feedback (DFB) dye laser on a monolithic poly(dimethylsiloxane) (PDMS) elastomer chip. The optical feedback was provided by a phase-shifted higher order Bragg grating embedded in the liquid core of a single mode buried channel waveguide. We achieved nearly 60nm continuously tunable output by mechanically varying the grating period with two dye molecules Rhodamine 6G (Rh6G) and Rhodamine 101 (Rh101). Single-mode operation was obtained with <0.1nm linewidth. Because of the higher order grating, a single laser, when operated with different dye solutions, can provide tunable output covering from near UV to near IR spectral region. The low pump threshold (< 1uJ) makes it possible to use a single high energy pulsed laser to pump hundreds of such lasers on a chip. An integrated array of five DFB dye lasers with different lasing wavelengths was also demonstrated. Such laser arrays make it possible to build highly parallel optical sensors on a chip. The laser chip is fully compatible with PDMS based soft microfluidics.

“…The micro-fluidic channel structure is fonned in 10 pm thick SU-8 photo-resist, and sandwiched between two Pyrex glass substrates. In the design of Helbo et al [2], the wafers were bonded together using a bonding layer of 10 pm thick SU-8. The present design relies on a new adhesive bonding technique, using an intermediate bonding layer of 5 pm thick poly-methylmethacrylate (PMMA).…”

“…This was achieved by integrating an existing microfluidic dye laser design by . Helbo et al [2,3] with a microfluidic diffusion mixer on a SU-8 based microfluidic chip. In this first demonstration, the lasing wavelength was tuned between 568 nm and 574 nm, using a solution of IO-* m o m Rhodamine 6G in ethanol, which was mixed with a pure ethanol in ratios from 1:l to 3:l.…”

We present a tunable microfluidic dye laser fabricated in SU-8. The tunability is enabled by integrating a microfluidic diffusion mixer with an existing microfluidic dye laser design by Helho et al. By controlling the relative flows in the mixer between a dye solution and a solvent, the concentration of dye in the laser cavity can he adjusted, allowing the wavelength to he tuned. Wavelength tuning controlled by the dye concentration was demonstrated with macroscopic dye lasers already in 1971, hut this principle only becomes practically applicable by the use of microfluidic mixing. With presently available dyes, the lasing wavelength can he tuned in an interval between 400 nm and 900 nm, depending on the specific dye. In this first. demonstration, the lasing wavelength was tuned between 568 nm and 574 nm, using a solution of m o m Rhodamine 6G in ethanol.,
