TRUMPF Boosts VCSELs Performance with New Sub-Wavelength Surface Grating Technology

TRUMPF, a global leader in VCSEL and photodiode solutions for data communication, has improved its proprietary subwavelength surface grating technology for datacom VCSELs. Subwavelength grating technology leads to better relative intensity noise (RIN) performance, reduces sensitivity against optical feedback and avoids polarization flips. As a result, the signal quality in a complex optical link is improved and enables higher data rates without changing the light current voltage (LIV) characteristics. This breakthrough technology with its benefits works for all offered wavelengths... read more
