“…The sensors trap light inside their microcavities, allowing the optical rays to resonate in the confined space aided by light coupling via optical waveguides. Optical resonators are used not only for biomedical detection [ 21 , 96 , 97 ] but also for gas detection [ 98 ], environmental control [ 87 ], toxin detection [ 99 ], temperature detection [ 70 , 100 ], microforce detection [ 67 ], single protein detection [ 90 ] and even nanoparticle detection [ 101 , 102 ].…”

Optical resonators are sensors well known for their high sensitivity and fast response time. These sensors have a wide range of applications, including in the biomedical fields, and cancer detection is one such promising application. Sensor diagnosis currently has many limitations, such as being expensive, highly invasive, and time-consuming. New developments are welcomed to overcome these limitations. Optical resonators have high sensitivity, which enable medical testing to detect disease in the early stage. Herein, we describe the principle of whispering-gallery mode and ring optical resonators. We also add to the knowledge of cancer biomarker diagnosis, where we discuss the application of optical resonators for specific biomarkers. Lastly, we discuss advancements in optical resonators for detecting cancer in terms of their ability to detect small amounts of cancer biomarkers.

“…The band gap of a PhC prohibits a band of wavelengths to propagate through the crystal and for this reason defects are introduced in the PhC so that the prohibited wavelengths can be propagated through the defects and this is the basic requirement to design a PhC based optical device. Recently, new fields of research based on optical sensing like force sensing, refractive-index sensing, temperature sensing, salinity sensing etc [7,8,9,10,11] are being explored. Basically, with the variation of the sensing parameter the variation in the refractive index (RI) and physical properties of material take place and this property of PhC makes it capable for sensing applications.…”

In this paper we investigate a new design of high sensitivity photonic crystal temperature sensor (PCTS). A square lattice of silicon (Si) rods immersed in air matrix is used as a basic structure. The designed sensor consists of two inline quasi-waveguides which are coupled to a resonant cavity (RC). The sensing principle is based on Si refractive index change caused by the variation of the temperatures over a range from 0 to 80 • C. This variation leads to an important shift in the resonance wavelength. The performance of the suggested temperature sensor has been analyzed and studied using finite-difference time domain (FDTD) method. The results show that our designed structure offers a high sensibility of 93, 61 pm/ • C and quality factor of 2506.5. Its structure is very compact with total size 115.422 µm 2 , which is suitable for nanotechnology based sensing applications.
