Magneto-controlled illumination with opto-fluidics

Non-Contact Opto-Fluidics-based Liquid Level Sensor for Harsh Environments

This paper presents a non-intrusive, non-contact liquid level sensor. The proposed sensor is a free-space-based optical sensor that uses opto-fluidic technology-based agile optics to direct light from a laser source to the Liquid Under Test (LUT). The presented design makes the proposed sensor ideal for use in environments where levels have to be determined for caustic or toxic liquids having a...

Chapter 5: Polarization-Independent Magneto-Optical Isolator Using TM-Mode Nonreciprocal Phase Shift

Non-Magneto-Optic Waveguide Isolator

We report on a novel technique to realize a waveguide optical isolator without using conventional magneto-optical materials and external magnets. The simulations are repeatedly performed using Beam Propagation Method (BPM) to confirm the accuracy. The simulation results show that the forward and backward propagations reach 2.54 and 15.68 dB, respectively.

Evaluation of On - chip Integration of Magneto - optic Isolators

The recent development of on chip integration of magneto-optic isolators is reviewed. Two major categories of structural designs for waveguide isolator (nonreciprocal mode conversion and nonreciprocal phase shift) have both merits and short comings for integration. The advances in integration techniques and materials related developments in the last decade are a big step towards monolithic inte...

Synthesis of bi-phase dispersible core-shell FeAu@ZnO magneto-opto-fluorescent nanoparticles

Bi-phase dispersible core-shell FeAu@ZnO magneto-opto-fluorescent nanoparticles were synthesized by a modified nanoemulsion process using poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (PEO-PPO-PEO) as the surfactant. The morphology and crystal structure of the nanoparticles were studied by TEM/HRTEM and XRD. The nanoparticles manifest soft ferromagnetic and/or n...
