We propose an efficient scheme of optical pumping and a compact design of an optically-pumped semiconductor optical amplifier (OP-SOA), with gain characteristics which are qualitatively similar to that of conventional (electrically-pumped) SOA. The o

Study of scattered light from a turbid medium is widely used to determine its scattering parameters, such as the interaction coefficient \(\mu_{t}\) and the anisotropy parameter \(g\). In practice, a turbid medium may comprise of more than one type o

We present a novel design of an optical switch based on grating-assisted non-linear directional coupler (GANDC) which consists of two non-identical waveguides, with a periodic refractive index perturbation in between the waveguides, along the directi

We propose a compact setup to determine the size and concentration of spherical particles in a turbid medium. A pair of plane mirrors is used to multifold the undeviated laser beam, and measure it at a detector placed close to the sample, to determin

Light scattering techniques are often used to characterize the particles suspended in a turbid medium, and Monte Carlo simulations are an important part of many such methodologies. In this work, we use the Monte Carlo method to simulate the propagati

We demonstrate an electrically controlled optical switch based on nematic liquid crystal (LC) core waveguide, fabricated on an ITO-coated glass substrate, with upper and lower cladding layers of the negative photoresist AZ15nXT. The reorientation of

We propose a novel scheme for injection of assist-light into the active region of a semiconductor optical amplifier (SOA) for fast gain recovery. In the proposed scheme, the assist-light is coupled into the active region of the SOA through an adjacen

We present a method to determine the anisotropy parameter g of a scattering liquid medium. A simple experimental setup is used to measure the scattered light from turbid samples, and a calibration curve is used to determine g. The interaction coeffic
