Silicon Nanotapers for Fiber-to-Waveguide Coupling

Two approaches for coupling light on a high-confinement chip with sub-micron waveguides are gratings or taper couplers. This application example…

Plasmonic Waveguide Filters with Nanodisk Resonators

Surface plasmon polaritons (SPPs) are waves trapped on the surfaces of metals owing to the interaction between the free electrons in a metal and…

BER Analysis of BPSK with RS Encoding

Demonstrates how to perform bit error rate (BER) testing for a binary phase-shift keyed (BPSK) optical system with Reed Solomon (RS) encoders and decoders.

LIDAR Systems Design

OptiSystem is an excellent tool for designing prototype designs of communications and sensor systems. The following application note demonstrates how OptiSystem can be used to design and simulate realistic models for light detection and ranging systems (LIDAR).

SER & BER Analysis of QAM-PSK-PAM Systems

Demonstrates how to perform symbol error rate (SER) or bit error rate (BER) testing for higher order modulation systems.

Photodiode Sensitivity Modelling

One of the main working parts of any optical receiver is the photodetector (which converts optical power to an electric current). Either a PIN or APD (avalanche photodiode) photodetector can be used depending on the system performance objectives.

The Optical Fiber Communication Conference and Exhibition (OFC) is the largest global conference and exhibition for…

Digital Modulation Analysis (FSK)

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…

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.

Power Combiner

Optical power in two or more waveguides can be combined onto a single waveguide…
