IMM Photonics brings polarization-maintaining VCSEL laser diode on the market

07 Feb 2024

IMM Photonics (Munich, Germany) has now extended its diverse portfolio of laser diodes to include an
efficient, low-cost and European-made niche product. The single mode VCSEL 850 nm laser diode
is contained in a compact TO46 housing. It can be used as a laser light source for optical
sensors in industry and life science, as a barcode reader in supermarkets, in range and velocity
measurements or for optical target marking (pointer).

“While traditional vendors have already withdrawn from the market for TO-housed VCSEL
laser diodes under this specification, we see very good market opportunities with our
innovative product.” Christian Raith, Managing director at IMM Photonics

What makes this product, manufactured on behalf of IMM Photonics, so special is the
polarization-maintaining characteristic of the laser diode. This essential feature is normally not
present with conventional VCSEL laser diodes. In addition, in contrast to conventional laser
diodes with an angular cross-section, the single mode VCSEL 850 nm has a round beam crosssection
– a property that is indispensable in many of the above-mentioned areas of
application. IMM Photonics is already planning to further expand its range of special VCSEL
laser diodes in response to feedback from the market.
