100 Gbps DP-QPSK System with Digital Signal Processing

The combination of polarization-multiplexing and quadrature phase-shift-keying (PM-QPSK or DP-QPSK) is emerging as one the most promising solutions to reach bit rates of 100 Gbps and higher.

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.


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.


OptiSystem C++ Component

OptiSystem’s Cpp Component, similar in operation to the MATLAB Component, allows users to create their own custom components. These are written in C++ and loaded into OptiSystem via dynamic link libraries (DLLs). The user has access to OptiSystem’s signal classes …

Optical Transmitters

The role of the optical transmitter is to: convert the electrical signal into optical form, and launch the resulting optical signal into the optical fiber.  The optical transmitter consists of the following components: optical source electrical pulse generator optical modulator …

LED Modulation Response

The frequency response of an LED is determined by the carrier dynamics (and therefore is limited by the carrier lifetime Tn) and the parasitic capacitance of the LED (described by the RC constant TRC[2]. If a small, constant forward bias is …

Semiconductor Laser Modulation Response

When using a directly modulated laser for high-speed transmission systems, the modulation frequency can be no larger than the frequency of the relaxation oscillations. The relaxation oscillation depends on both carrier lifetime and photon lifetime. The approximate expression of this …
