VPIcomponentMaker^TM Active Photonics

PIcomponentMaker^TM Active Photonics is an integrated design environment for active photonic circuits and advanced semiconductor lasers. VPIcomponentMaker^TM Active Photonics uses unique large-signal bidirectional-signal time-domain algorithms based on over 17 years research in time-domain laser modeling (the TLLM). These models can predict the complex nonlinear dynamics of multi element circuits and lasers over wide optical bandwidths.

Applications

• Design integrated tunable lasers, based on DBR/Active/DFB/GC/Passive sections for tuning dynamics and stability
• Investigate optimum mixes of gain, loss and index coupling for spectral stability, feedback insensitivity and power in high-power lasers
• Enhance modulation speed using MQW materials, gain coupling and optimized drive waveforms for high-speed lasers
• Investigate the spectral stability and modulation dynamics of bulk-grating or FBG stabilized lasers
• Quantify anti-reflection coating specifications by simulating the full interaction of laser and modulator
• Simulate active, passive, ring and hybrid mode-locked lasers, to determine amplitude and timing stability of ultra-fast sources
• Develop fast switches, optical logic, modulators, detectors, edge detectors, gain flatteners, semiconductor line amplifiers and semiconductor preamplifiers
• Compare XPM, XGM and FWM wavelength conversion technologies for speed, noise and conversion range
• Develop 2R and 3R regenerators and optimize their speed, transfer characteristics and induced chirp
• Simulate full dynamics including spectrum evolution, dynamic/adiabatic/SHB chirp, turn-on jitter, intensity noise and patterning due to deep modulation
• Predict instabilities due to physical processes, such as spatial-hole-burning in lasers.
