“…Subwavelength grating (SWG) WGs were highly desirable as they could tailor the effective index and dispersion characteristics of the driven mode. SWG WG-based RRs were highly sensitive due to the enhanced light-matter interaction [40,41,44,45]. In [46], a 30 µm diameter SWG RR was realized for biosensing applications.…”

“…The SEM picture of the fabricated RR is displayed in Figure 3b along with a magnified image of a segment, which is shown in the inset of the figure. Several interesting results were obtained by employing a double SWG WG RR configuration [44]. A non-contact piezoelectric (inkjet) method for the quick and effective printing of bioactive proteins, glycoproteins, and neoglycoconjugates onto a high-density Si µ-RR biosensor array was demonstrated as shown in Figure 3c [47].…”

Optical sensors for biomedical applications have gained prominence in recent decades due to their compact size, high sensitivity, reliability, portability, and low cost. In this review, we summarized and discussed a few selected techniques and corresponding technological platforms enabling the manufacturing of optical biomedical sensors of different types. We discussed integrated optical biosensors, vertical grating couplers, plasmonic sensors, surface plasmon resonance optical fiber biosensors, and metasurface biosensors, Photonic crystal-based biosensors, thin metal films biosensors, and fiber Bragg grating biosensors as the most representative cases. All of these might enable the identification of symptoms of deadly illnesses in their early stages; thus, potentially saving a patient’s life. The aim of this paper was not to render a definitive judgment in favor of one sensor technology over another. We presented the pros and cons of all the major sensor systems enabling the readers to choose the solution tailored to their needs and demands.

In this paper, a novel and cost-effective photonic platform based on silica–titania material is discussed. The silica–titania thin films were grown utilizing the sol–gel dip-coating method and characterized with the help of the prism-insertion technique. Afterwards, the mode sensitivity analysis of the silica–titania ridge waveguide is investigated via the finite element method. Silica–titania waveguide systems are highly attractive due to their ease of development, low fabrication cost, low propagation losses and operation in both visible and near-infrared wavelength ranges. Finally, a ring resonator (RR) sensor device was modelled for refractive index sensing applications, offering a sensitivity of 230 nm/RIU, a figure of merit (FOM) of 418.2 RIU−1, and Q-factor of 2247.5 at the improved geometric parameters. We believe that the abovementioned integrated photonics platform is highly suitable for high-performance and economically reasonable optical sensing devices.

“…The silicon waveguide core is then hovering in the air, only supported by a series of silicon strips to the remaining lateral silicon walls. Such silicon strips have an optical purpose besides holding the waveguide core and providing mechanical stability; they act as a subwavelength grating cladding that provides the index contrast necessary for waveguiding [15]. The schematic of SMW is shown in Fig 1. The height and width of the core are denoted as Hcore and Wcore, respectively.…”

In this letter, we present a numerical study on the designing of silicon-on-insulator (SOI) suspended membrane waveguide (SMW). The waveguide geometry is optimized at 3.39 µm TE-polarized light which is the absorption line of methane gas by utilizing a 3D finite element method (FEM). The transmission loss (TL) and evanescent field ratio (EFR) of the waveguide are calculated for different geometric parameters such as the width of core, the height of core and period of the cladding. We found out that TL is directly related to EFR. Therefore, a waveguide geometry can be designed which can offer high EFR at the cost of high TL or low EFR with low TL, as desired. Based on the geometric parameters used in this paper, we have obtained a TL and EFR which lies in the range of 1.54 dB-3.37 dB and 0.26-0.505, respectively. Full Text: PDF ReferencesL.
