Transceiver Laser Diode
Laser diodes are the heart of optical modules—they convert electrical signals into light for fast and efficient fiber-optic communication. Optical transceivers rely on integrated lasers to deliver precise, reliable, and high-bandwidth signal transmission. The capabilities of the transmitter are largely dependent on its design. Get 100 mW of uncooled output power and 300 mW of output power when cooled, to enable 100 Gbps and 200 Gbps per lane, respectively, for cutting-edge O-band transceivers. That “engine” is the laser diode in optical fiber communication. Whether it is diodes for extremely high reliability applications such as LiDAR pumping or high-power pump modules for industrial and security applications, or customized laser diodes for scientific applications, TRUMPF Photonics is your OEM design and manufacturing partner of choice.
