Herein, we have discussed three major methods which have been generally employed for
the generation of optical beams with orbital angular momentum (OAM). These methods …

Biosensors have opened up new possibilities for the detection of several environmental
risks and diagnosis of numerous diseases. They have opened a new era in which heavy …

Surface plasmon resonance (SPR) and surface plasmon polariton (SPP) is substantially
developing optical sensing approaches that have been working in a wide range of …

In the past few decades, several methods concerning optical thin films have been
established to facilitate the development of integrated optics. This paper provides a brief …

In the last two decades, biosensors have made a remarkable development in the area of
food quality monitoring, drug discovery, environmental monitoring, soil quality monitoring …

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 …

A Bragg grating (BG) is a one-dimensional optical device that may reflect a specific
wavelength of light while transmitting all others. It is created by the periodic fluctuation of the …

Silicon photonic (SiP) evanescent-field biosensors aim to combine the information-rich
readouts offered by lab-scale diagnostics, at a significantly lower cost, and with the …

We demonstrate a reconfigurable optical bandpass filter based on subwavelength grating
(SWG) waveguide operating in the Bragg reflection regime and integrated with a cavity of …

Exploration and implementation of silicon (Si) photonics has surged in recent years since
both photonic component performance and photonic integration complexity have …
