Engineering photonic devices from liquid has been emerging as a fascinating research avenue. Reconfigurably tuning liquid optical micro-devices are highly desirable but remain extremely challenging because of the fluidic nature. In this article we demonstrate an all-liquid tunable whispering gallery mode microlaser floating on a liquid surface fabricated by using inkjet print technique. We show that the cavity resonance of such liquid lasers could be reconfigurably manipulated by surface tension alteration originated from the tiny concentration change of the surfactant in the supporting liquid. As such, remarkable sensing of water-soluble organic compounds with a sensitivity of free spectral range as high as 19.85 THz / (mol · mL−1) and the detectivity limit around 5.56 × 10−3 mol · mL−1 is achieved. Our work provides not only a novel approach to effectively tuning a laser resonator but also new insight into potential applications in biological, chemical and environmental sensing.

“…The broad cavity size dispersion from 15 to 120 µm is a result of the manual fabrication process which could be improved by an automatic deposition, as for example by ink-jet printing. [38] The size-distribution presented can be controlled during the emulsion processing by changing droplet volume.…”

Biolasers obtained from biomaterials are attracting a wealth of interest for their potential as future biosensors with enhanced sensitivity, and advanced cell tracking. Here, miniature biolasers are reported, which are formed by bovine serum albumin (BSA) protein and biosourced polysaccharides derived from land plants such as cellulose and pectin. Using a green processing route aided by simple emulsions, solid-state microspheres with diameters of 15–100 µm are fabricated and utilized as whispering gallery mode lasers with thresholds of a few µJ mm–2 and quality factors of up to 3000. Furthermore, BSA microlasers are found to be compatible with cell growth and resistant to the aqueous environment of cell culture media. This environmentally friendly and biocompatible design shows promise for future implantable biosensing devices opening a path between laser science and medicine

“…The Q factor is higher compared to microdroplet lasers. Based on this achievement, Sun's group developed more fascinating methods to obtain hemispheres with precise control of their size and position using a microplotter system . Furthermore, promising applications based on these microstructures were also studied such as single mode lasers, chemical vapor sensing, green quantum dot laser, and fluorescence‐based temperature sensors …”

Soft‐matter microlasers are an interesting part of soft‐matter photonics, which are based on liquids, liquid crystals, polymers, biological materials, and fabricated mainly by solution‐processing approaches. Soft‐matter microlasers comprehend a multitude of attractive features, including low‐cost, mechanical flexibility, wide range wavelength tunability and, in some cases, biocompatibility, and biodegradability. As such, they are recognized as versatile candidates for efficient light sources with enhanced performances and applications as ultrasensitive physical, chemical, and biological sensors. Here, the recent developments of soft‐matter microlasers are reviewed in time and the prospect in this field is provided. First, the characteristics of the representative soft‐matter microlasers are discussed with focus on their laser structures, lasing mechanisms, fabrication approaches, and gain material origins, followed by an introduction about the current cutting‐edge soft‐technologies that are applied in soft‐matter microlasers. Afterward, their potential applications as wavelength tunable sources, sensors, and displays are highlighted. Finally, the work is summarized and the prospect of soft‐matter microlasers for expanding this emerging research field is presented.
