“…Of course, one can detect the change of the surrounding refractive index by immersing the microdisk in different analyte fluids [192][193][194][195][196][197][198][199]. Microdisks have also been tested as displacement sensors [200], gamma ray sensors [201], gas sensors [202], surface curvature sensors, [203] and of course as biosensors [194,197,[204][205][206][207][208][209][210]. Each of these applications will be briefly discussed.…”

Single-waveguide-based microresonators for optical sensing

Optical biosensors with a high sensitivity and a low detection limit play a highly significant role in extensive scenarios related to our daily life. Combined with a specific numerical simulation based on the transfer matrix and resonance condition, the idea of novel single-waveguide-based microresonators with a double-spiral-racetrack (DSR) shape is proposed and their geometry optimizations and sensing characteristics are also investigated based on the Vernier effect. The devices show good sensing performances, such as a high quality factor of 1.23 × 10 5 , a wide wavelength range of over 120 nm, a high extinction ratio (ER) over 62.1 dB, a high sensitivity of 698.5 nm/RIU, and a low detection limit of 1.8 × 10 −5 . Furthermore, single-waveguide-based resonators can also be built by cascading two DSR structures in series, called twin-DSRs, and the results show that the sensing properties are enhanced in terms of quasi free spectral range (FSR) and ER due to the double Vernier effect. Excellent features indicate that our novel single-waveguide-based resonators have the potential for future compact and highly integrated biosensors.

Optical sensors based on resonant whispering gallery mode (WGM) optical cavities are discussed in the context of recent research developments. WGM-based sensors are among the most sensitive optical sensing devices currently known, especially when combined with surface plasmon effects. The basic theory of WGM "reactive" sensing is first discussed, along with the basic parameters that are used to characterize such devices (i.e., sensitivity, signal-to-noise ratio, and detection limit). Surface chemistry methods are of critical importance for targeted sensing applications and the fundamentals of this aspect are examined. The performance of fluorescent WGM-based devices is compared to state-of-the-art "evanescently-coupled" structures. Finally, the performance of WGM-based optical sensors is compared and contrasted to a range of alternative optical microsensor technologies currently under development.A. François
