TRUMPF breakthrough in sub-wavelength grating reducing RMS and RIN values
TRUMPF Photonic Components GmbH of Ulm, Germany (part of the TRUMPF Group) – which makes vertical-cavity surface-emitting lasers (VCSELs) and photodiodes for the consumer electronics, datacoms, industrial sensing & heat treatment and automotive markets – is showcasing its recently updated VCSEL product portfolio and technology with matching photodiodes in booth 641 at the European Conference on Optical Communications (ECOC 2023) in Glasgow, Scotland, UK (2–4 October).
The firm is expanding its product portfolio beyond the well-established 25G and 56G components with higher data rates (up to 100G), longer wavelengths, extended temperature ranges and higher performance. “We continuously strive and make investment to pursue new technologies that improve the performance of our VCSELs and photodiodes in the datacom field,” says Ralph Gudde, VP marketing & sales. “Our newest breakthrough in sub-wavelength grating is designed to reduce RMS and RIN values for our multi-mode and single-mode VCSELs, enabling a lower bit-error rate (BER) for data transmission over longer fiber,” he adds.
TRUMPF is investing in several technologies to improve the power, cost and reliability benefits of VCSELs for future applications. The developments include long-wavelength VCSELs and single-mode VCSELs with polarization gratings. The long wavelengths span 980nm to 1310nm and even higher, addressing longer-range datacom and automotive applications. Increased bandwidth, lower power consumption, additional multiplexing options and superior noise control are among the expected benefits of the development of single-mode VCSELs and polarization gratings. The solutions continue to offer transmission at higher data rates and higher temperatures, resulting in improved overall system performance.
