Highly sensitive silicon photonic temperature sensor based on liquid crystal filled slot waveguide directional coupler.

Optics Express, 2020
A highly sensitive silicon photonic temperature sensor based on silicon-on-insulator (SOI) platform has been proposed and demonstrated. A two-mode nano-slot waveguide device structure cladded with a nematic liquid crystal (LC), E7, was adopted to ...

Slot-waveguide biochemical sensor

Optics Letters, 2007
We report an experimental demonstration of an integrated biochemical sensor based on a slot-waveguide microring resonator. The microresonator is fabricated on a Si3N4-SiO2 platform and operates at a wavelength of 1.3 microm. The transmission spectrum of the sensor is measured with different ambient refractive indices ranging from n=1.33 to 1.42.

An ultracompact 3×1 MMI power-combiner based on Si slot-waveguide structures

, 2020
Today, photonic integrated circuits (PIC) that work with a high-modulation speed (100Gb/s and beyond) are required to use more optical power to overcome the losses. One solution is to use a high-level laser with a hundred milliwatts power. However, for a

A highly sensitive design of subwavelength grating double-slot waveguide microring resonator

Laser Physics Letters, 2020
We presented a novel design of a microring resonator based on a subwavelength grating (SWG) double-slot waveguide (WG) due to its enhanced sensitivity. The paper is divided into two parts.
