17 May 2006 VPIcomponentMaker Active Photonics is an integrated design environment for active photonic circuits and advanced semiconductor lasers. It 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
- Model multiple sections semiconductor lasers, and lasers with longitudinally dependent parameters (e.g., tapered lasers, FBG stabilized lasers).
- Quantify anti-reflection coating specifications by simulating the full interaction of laser and modulator
- Simulate active, passive, ring and hybrid modelocked lasers, to determine amplitude and timing stability of ultra-fast sources
- Develop fast switches, optical logic, modulators, detectors, edge detectors, gain flatteners, and semiconductor amplifiers
- 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 laser dynamics: spectrum evolution, dynamic/adiabatic/SHB chirp, turn-on jitter, intensity noise and patterning
- Predict instabilities due to physical processes, such as spatial hole burning
- Extract laser parameters from simple laboratory measurements, explore design variations (adding an external cavity) based on the real device.
