Optiwave Systems, a provider of photonic design automation tools, offers OptiSPICE, a specialized software platform designed for the design and simulation of optoelectronic circuits that combine optical and electronic components. The software enables engineers to model complex circuits at the transistor level, including components such as laser drivers, optical interconnects, transimpedance amplifiers, and electronic equalizers.

OptiSPICE is built to bridge the gap between electronics and photonics by allowing both optical and electrical elements to be simulated within a single framework. As photonic integrated circuits increasingly incorporate electronic control and signal-processing components, the software provides a unified simulation environment capable of predicting signal behavior across these interacting domains.

The platform supports a wide variety of circuit elements and models, including electronic devices such as diodes, BJTs, and MOSFETs, as well as optical components such as laser diodes, optical fibers, and photodiodes. Through a single simulation engine, engineers can perform transient time-domain simulations, frequency-domain analysis, and noise analysis to evaluate system performance and signal integrity.

OptiSPICE also incorporates tools for schematic capture, parameter extraction, and waveform visualization. Designers can analyze electrical and optical signals through built-in waveform viewers and advanced visualization functions that display parameters such as voltage, current, optical power, phase, and spectral characteristics. This integrated workflow helps engineers refine device parameters and optimize circuit performance before fabrication.

Another key capability of the software is its ability to generate self-consistent solutions for circuits containing both optical and electrical feedback loops, which are common in modern optoelectronic systems. By accurately modelling interactions between the two domains, OptiSPICE enables reliable simulation of advanced systems such as high-speed modulators, optical phase-locked loops, LiDAR circuits, and sensing platforms.

With applications spanning fiber-optic communication, sensing technologies, photonic integrated circuits, and advanced optoelectronic system design, OptiSPICE provides engineers and researchers with a comprehensive environment for developing next-generation optical and electronic systems.
