Crosslight would like to announce an update to our current official release (v2025). In addition to multiple bug fixes, the following improvements were made:
- A new optional module that implements a small-signal Photon-Photon resonance model for edge-emitting DFB/DBR lasers.
- A new model for single-photon avalanche photodetectors.
- A new method of transient simulation, using relative time periods for each individual scan command.
This is helpful when dealing with intervals that vary significantly between scans. - A new decoupled split-step thermal model, which can help with convergence at the cost of a small loss of self-consistency.
- A revised exciton model.
- A new mesh generator interface and improved regridding methods.
- A triplet-triplet fusion model for OLEDs.
- Improved PCSEL models to compute the coupling coefficients of a unit cell.
- An optional speed-up to microcavity simulations, by limiting printing of diagnostic data.
Customers with an up-to-date maintenance contract will be issued this update in the next few days.
