Signal Quality Ratios

When designing or analyzing the performance of an analog or digital link, the following signal metrics are commonly used…

Optical Receiver Analysis (PIN-TIA-LA)

The overall performance of a point-to-point optical communication link is normally defined based on the minimum average optical power, measured at the input to the optical receiver…

Matched Filter Analysis

A matched filter is an ideal filter which acts upon a received signal so as to maximize its signal to noise ratio (SNR). Under conditions of additive white Gaussian noise, the SNR…

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…

MATLAB Data Formats

This application note will describe the Matlab Data Formats that are available within OptiSystem.

OptiSystem Matlab Data Formats

The data structure for all input and output ports and all variables declared within the MATLAB m-file can be viewed from the MATLAB workspace To access the workspace, first select Load MATLAB from the MATLAB Component and select OK. This action pre-loads MATLAB (it will stay open unless it is manually closed) After running a…

Optical Coherent Receiver Sensitivity Analysis

Optical coherent receiver technology can provide theoretical sensitivity levels to the order of 10’s of photons/bit. This application note provides an overview of common coherent receiver architectures…

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…

40 Gbps Silicon Depletion Mode TW Modulator

Traveling wave modulators are widely used for their low power consumption and high speeds. In this application note a transmission line model is combined with an optical…

Symmetric Lossless X Coupler

The X Coupler is a basic component used in many kinds of optical circuits. Here its properties are analysed by theoretical means, and also by detailed simulation of…
