Optofluidic Resonators and Sensors
Optofluidic resonators are optical microcavities that are partially or completely made of liquids. Sensors based on optofluidic resonators use either passive cavity resonance shift or active lasing to detect small changes in refractive index, absorption, gain, or scattering in the vicinity of the resonator.
Optofluidics refers to the synergistic fusion of microfluidics and photonics [1, 2]. By integrating photonic and fluidic functions on a single chip, optofluidics not only gives rise to highly compact and integrated microsystems but also enables novel adaptive and reconfigurable photonic devices via microfluidic liquid manipulation. Although both photonics and fluidics have been independently miniaturized within the past three decades, it was not until very recently that the monolithic integration of the two became possible. Today, the channel dimensions in microfluidic devices have become comparable to or even smaller than the...
