TRUMPF presents controlled-polarized VCSEL at Photonics West

In booth 327 at the Photonics West fair 2022, TRUMPF Photonic Components GmbH of Ulm, Germany (part of the TRUMPF Group), which manufactures vertical-cavity surface-emitting lasers (VCSELs) and photodiodes for the consumer electronics, datacoms, industrial sensing, heating and automotive markets, is presenting a live showcase of VCSELs with controlled polarization for illumination applications.

The new VCSEL should lead to much smaller construction space needed in, for example, smartphones for 3D scene illumination. Together with Metalenz, a Boston-based pioneer in designing and commercializing meta-optics, TRUMPF demonstrates how future consumer electronic devices benefit from these smaller and smarter components. This technology progress is enabled through the development of VCSELs with stable polarization.

Extended VCSEL portfolio

At Photonics West, TRUMPF is also presenting its portfolio of single-mode and multi-mode VCSELs, which can be used for a wide range of advanced industrial and consumer sensing applications, from oxygen sensor to face recognition.

The portfolio includes a new single-mode VCSEL for highly precise time-of-flight sensors. With ViBO (VCSEL with integrated backside optics) TRUMPF is showcasing another new VCSEL solution that comes with monolithically integrated micro-optical elements. This technology benefits applications such as light detection & ranging (LiDAR) or augmented reality (AR) glasses, as ViBO comes with a significantly reduced footprint and offers great freedom in design, as tailored illumination profiles can be created.

VCSEL for industrial heating and data communication

The VCSEL heating systems showcased at the show enable direct heat treatment with fully controllable emission zones. They offer what is reckoned to be huge potential for various industrial applications – from more sustainable Li-battery production to local softening of metal automotive parts to photovoltaic applications. In the production of Li-batteries for example, they enable faster and more energy-efficient drying of active material and therefore a much more efficient production process. The modules are highly flexible and compact, enabling high efficiency and quality.

The portfolio of TRUMPF Photonic Components is completed by VCSEL and photodiode solutions for optical communications. Media transmission via fiber optical communication is a growing field, as the amount of data that has to be transferred is increasing. The solutions offer high date rates at low power consumption and low latency to fulfill the highest demands of data centers.
