INTRODUCTION TO PLANAR WAVEGUIDE OPTICAL SENSOR

Planar optical waveguide core

Planar optical waveguide core

The waveguide consists of a semi-infinite slab of dielectric materials with thickness d and refractive index n 1 (the core) that is sandwiched between two regions (the cladding) both of refractive index n 2, and where n 1>n 2. One essential el-ement is the guiding of the optical radiation in waveguides for integrated optical devices and optical fibers for long distance transmission. The same mathematical ideas can be applied (with minor modifications) to circular waveguides. The waveguide core size of the fundamental mode in the waveguide direction (y axis) can be enlarged to 400 μm by introducing the refractive index matching and mode competition, to increase single-pass gain of the waveguide while ensuring good beam quality in the y -axis direction.

Planar Optical Waveguide Technology

Planar Optical Waveguide Technology

Planar waveguides are optical waveguides with a planar geometry that confine light propagation to a single dimension. They are often fabricated in the form of a thin transparent film with increased refractive index on some substrate, or possibly embedded between two substrate layers. FIMMPROP is probably the most widely used propagation tool for the modelling of silicon photonics: rigorous (no slowly varying approximation), fully vectorial, offering wide angle capability and very high design flexibility.

Three-layer planar optical waveguide

Three-layer planar optical waveguide

A three layer planar waveguide structure, consisting of a light guiding ferroelectric lead zirconate titanate thin film, embedded between two transparent zinc oxide electrodes, was elaborated and studied by m-lines spectroscopy. A comparison has been made between the physical-optic approach and the ray-optic approach in descr bing light propagation in a waveguide. However, unlike electrical current that flows through a metal strip according to Ohm's law, optical waves.

Introduction to the 40G Optical Module

Introduction to the 40G Optical Module

In data centers and enterprises, 40G QSFP+ series optical transceiver modules are generally used to build 40G network connectivity solutions. The modules most commonly used in 40G solutions include 40GBASE-LR4 QSFP+, 40GBASE-SR4 QSFP+, and 40G LR4 PSM. In this article 10Gtek will be introducing different network solutions of the most. 40G optical module refers to the transmission rate of 40Gbps, CFP and QSFP are its main packaging form, and 40G QSFP+ optical module is one of the more widely used. 40G QSFP+optical module is dedicated to high-density application systems, with higher port density and lower overall system cost compared to traditional SFP+optical modules. Due to the differences in various parameters, the application range is also different.
