Optical System — Photonic Crystal Fiber Supercontinuum Generation

a photonic crystal fiber supercontinuum generation schematic

Abstract Photonic crystal fiber (PCF) provides a unique platform for realizing the desired dispersion, birefringence, confinement, and mode multiplicity characteristics from a supercontinuum light source for myriad applications. This can be attributed to the freedom in designing the shape, size, and arrangement of holes and material composition of the PCF. Using the vector finite element…

FBG Fiber Loop Mirror Sensor Design Basics

Fiber loop mirror configurations have been used in several different applications. One important application is sensing. Inserting a Fiber Bragg Grating (FBG) in the fiber loop mirror allows exploiting the switching feature of the loop mirror to enable enhanced sensing and accessing capabilities.

Digital Modulation Analysis (PSK)

Digital modulation systems are used to transmit digital (quantized) information over a medium such as air or optical fiber. Transmission is achieved by mapping the information…

Ring Resonator Fiber Optic Gyroscope

This application note demonstrates the shift in resonant frequency in an optical ring resonator due to Sagnac effect and how a closed loop feedback system can be used to calculate the angular…

Fiber Optic Gyroscope (FOG) Systems Design

Fiber optic gyroscopes, using the Sagnac effect, can rapidly and accurately sense changes in orientation (angular velocity) from interferometric measurements. Two open loop detection techniques, DC and phase modulation, are demonstrated using OptiSystem.

Single Mode Fiber

In this example, we will show you how to simulate a simple single-mode optical fiber that is optimized for use in the 1310 nm wavelength region. The main features of OptiFiber will be addressed in this example. You can find this example as the SMF- 28.fcd file in the Samples directory. Defining fiber profile To…

Real Fiber Sample

OptiFiber 1.5 directly supports experimental reference. index profiles scanned with the NR-9200 optical fiber analyzer from EXFO Inc. The fiber parameters calculated in that way provide indispensable feedback information to the product designer and reduce the optimization cycle and the time-to-market. The experimental profile “FromNR9200.asc” and the OptiFiber project “FromNR9200.fcd” used in this lesson can…
