(CLEO). Conference on Lasers and Electro-Optics, 2005., 2005 Recent advances in the development of lab-on-a-chip devices have been rapid and broad ranging. In general however these devices, while containing micro- or even nano-scale components, rely heavily on macroscale infrastructure (e.g. microscopes, chip readers and power sources) to perform much of the actual product detection and subsequent analysis.

Birefringent optofluidic gratings
Optics Express, 2020 A set of parallel microfluidic channels behaving as a diffraction grating operating in the Raman-Nath regime has been fabricated and studied. The diffraction efficiency of such structure can be tuned by selecting a liquid with a particular refractive index and/or optical anisotropy.

Nonlinear Photonics, 2006 Optofluidics refers to a class of adaptive circuits that integrate optical and fluidic devices. Familiar examples include liquid crystals and dye lasers. The introduction of liquids in the optical structure enables flexible fine-tuning and reconfiguration of circuits so they can perform tasks optimally in a changing environment.

Quantum dot enabled thermal imaging of optofluidic devices [PDF]
, 2012 Quantum dot thermal imaging has been used to analyse the chromatic dependence of laser-induced thermal effects inside optofluidic devices with monolithically integrated near-infrared waveguides. We demonstrate how microchannel optical local heating plays

Proof-of-principle of surface detection with air-guided quantum cascade lasers [PDF]
, 2008 We report a proof-of-principle of surface detection with air-guided quantum cascade lasers. Laser ridges were designed to exhibit an evanescent electromagnetic field on their top surface that can interact with material or liquids deposited on the device.

Highly dispersive photonic band-gap-edge optofluidic biosensors [PDF]
, 2006 Highly dispersive photonic band-gap-edge optofluidic biosensors are studied theoretically. We demonstrate that these structures are strongly sensitive to the refractive index of the liquid, which is used to tune dispersion of the photonic crystal.
