Photon DesignPhoton Design is offering LASFIT, a laser diode parameter extractor program designed to extract as much data as possible from simple experimental measurements on a distributed feedback (DFB) laser. After the user supplies one measurement of a laser's spectrum just below threshold, the program gives estimates for up to 14 parameters including facet reflectivities, facet phases and refractive index coefficients. The extracted parameters then can be fed back into a CAD model for further device simulation. The program works automatically with the company's i-CLADISS laser diode simulator and is...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra September 2022 IssuePower DetectorsThe HP60A-15KW-GD-QBH power detector series from Gentec Electro-Optics Inc. is designed for the measurement of fiber lasers with powers of up to 15 kW.
