OptiSPICE Overview Video

OptiSPICE 5.0 introduces new electrical models for characterizing hetero-structure bipolar transistors (Mextram and Agilent), a physical model for spiral inductors (for Si and III-V based substrates), and a new Waveguide Crossing device.

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…

Dispersion Shifted Fiber

In this example, we will show you how to simulate optical fiber that has a triangular with annular ring profile. In addition, we will show you how to optimize given fiber profile to have zero dispersion at 1550 nm by the powerful parameter scan routines of OptiFiber. You can find this example as the DSF.fcd…

Fiber Bragg Grating

In the first lesson, you will learn how to design a Fiber Bragg Grating with chirp and apodization. Such a grating finds application in fiber dispersion compensation. S.1 The first thing you will do is to open a new project. Then, you will choose one of the five available modules to work with: Single Fiber,…

Sensors

In this lesson, you will use the Fiber Bragg Grating example from Lesson 1. Have a
look at the Profile graph…

Reconstruction of Unknown Grating

In this lesson we check that the layer peeling algorithm can reconstruct an unknown grating with knowledge of only the reflection coefficient. In the first step, we select a typical grating with chirp and apodization and calculate its reflection coefficient. This spectrum is then exported to a text file. In the next step, OptiGrating is…

Electroabsorption Modulator

In this tutorial, we demonstrate optical modulation using an electroabsorbtion modulator. Sample: Electroabsorption Modulator.osch The EA Modulator device is located in the OptoElectric library. It has 2 electrical ports for the bias and RF driving and 2 optical ports as an input and output. The EA modulator is driven with a voltage source device which…

Ring Switch

In this tutorial, we demonstrate a ring switch that adds or drops channels by controlling the index of a ring resonator. Sample: RingSwitch.osch Figure 1: Schematics of Ring Switch The ‘LaserBlck’ is a subcircuit block that contains a circuit for driving laser diode. The laser diode is also connected with a thermal network consisting of…
