“…Xiao et al, 2016 demonstrated polymer-based MZI for the applications of switching circuits, however, this device exhibits asymmetric structures. Lin et al, 2019 designed and fabricated an asymmetric polymer-based MZI sensor, however, the thickness of this device is 4 µm, which is comparatively higher and creates warpage during curing of the waveguides, resulting in high coupling loss.…”

We propose a Mach-Zehnder interferometer (MZI) which consists of a taper, a bending waveguide, and two symmetrical arms. The structure is realized with organic-inorganic hybrid polymer materials and analyzed by a commercially available RSoft CAD BeamPROP solver. We set the core width for input and output of the Mach-Zehnder interferometer at 6 µm for single-mode propagation. This interferometer shows an excess loss of 0.162 dB and has an efficiency of almost 96.4%. We also investigate the polarization dependency of this interferometer varying the beam incident angles from 0-30 degrees and this investigation suggests that this MZI shows polarization dependency when the light incident on the launched side of this MZI at for transverse electric (TE) and transverse magnetic (TM) modes.

“…Ever since, a major advancement has been made in the manufacturing of MZI sensors. Various structures have been successfully developed using a range of fabrication materials, like Si 3 N 4 [24], TiO 2 [25], Si [26], and polymers [27] with a detection limit (DL) of 10-6 to 10 −7 RIU. Alternatively, chip-incorporated Young's interferometers (YIs) demonstrated the aptitude to detect biomolecules, resulting in a DL that was comparable to the MZI sensor [28].…”

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.

This study presented an overview of current developments in optical micro-electromechanical systems in biomedical applications. Optical micro-electromechanical system (MEMS) is a particular class of MEMS technology. It combines micro-optics, mechanical elements, and electronics, called the micro-opto electromechanical system (MOEMS). Optical MEMS comprises sensing and influencing optical signals on micron-level by incorporating mechanical, electrical, and optical systems. Optical MEMS devices are widely used in inertial navigation, accelerometers, gyroscope application, and many industrial and biomedical applications. Due to its miniaturised size, insensitivity to electromagnetic interference, affordability, and lightweight characteristic, it can be easily integrated into the human body with a suitable design. This study presented a comprehensive review of 140 research articles published on photonic MEMS in biomedical applications that used the qualitative method to find the recent advancement, challenges, and issues. The paper also identified the critical success factors applied to design the optimum photonic MEMS devices in biomedical applications. With the systematic literature review approach, the results showed that the key design factors could significantly impact design, application, and future scope of work. The literature of this paper suggested that due to the flexibility, accuracy, design factors efficiency of the Fibre Bragg Grating (FBG) sensors, the demand has been increasing for various photonic devices. Except for FBG sensing devices, other sensing systems such as optical ring resonator, Mach-Zehnder interferometer (MZI), and photonic crystals are used, which still show experimental stages in the application of biosensing. Due to the requirement of sophisticated fabrication facilities and integrated systems, it is a tough choice to consider the other photonic system. Miniaturisation of complete FBG device for biomedical applications is the future scope of work. Even though there is a lot of experimental work considered with an FBG sensing system, commercialisation of the final FBG device for a specific application has not been seen noticeable progress in the past.
