Photon Design providing PCL and PCSEL design software
Photonic simulation CAD software developer Photon Design Ltd of Oxford, UK is now providing a photonic-crystal surface-emitting laser (PCSEL) and photonic crystal laser (PCL) design solution for laser designers, by using a combination of its HAROLD and OmniSim simulation tools. Existing HAROLD users can add OmniSim to begin designing crystal lasers.
PCSELs and PCLs are rapidly becoming the first choice of laser for high-power, coherent applications in fast-growing markets, such as optical communications, sensing, and material processing, says the firm. They have complex crystal structures that are challenging to model. However, that is now possible, entirely within Photon Design’s simulation tool portfolio.
“Engineers designing PCSELs and PCLs can use Photon Design’s HAROLD to simulate gain spectra in epitaxy structures. OmniSim, our FDTD (finite-difference time domain)-based, dynamic gain modeler, then simulates pulsed laser light propagation, over time, through the laser crystal lattice, including the effect of power,” notes CEO Dr Dominic Gallagher.
“OmniSim’s Dynamic Gain modeller is new. Its Band Analyser provides band diagrams for photonic crystals, enabling designers to tune the laser structure to the desired wavelength, optimizing the lattice, atoms and cavities in the structure using our Kallistos simulator,” he adds. “Finally, active FDTD simulations provide the operating wavelength and linewidth of the laser, which our Q-factor calculator produces at up to 85% quicker than the conventional, Fourier-transform method, with equivalent levels of accuracy.”
