indie (Former EXALOS), the world’s leading manufacturer of Superluminescent Light-Emitting Diodes (SLEDs), has been selected as a finalist for the prestigious SPIE Prism Award 2025, which will be handed out at the upcoming SPIE Photonics West in January next year.
The annual event, which will be celebrating its 17th year, recognizes commercialized innovation in photonics, honoring companies that are bringing transformative products to market.
Among the distinguished finalists, EXALOS is the only company from Switzerland.
The nominated, advanced 14-pin Butterfly (BTF) module emits an optical spectrum with 3dB bandwidth of 33 nm around a center wavelength of 1549 nm. The output is collimated into three output beams that are propagating through an optical circulator before being focused into an array of three PM output fibers. Efficient beam collimation, low-loss beam propagation on the optical bench in combination with high-efficiency coupling to the PM output fibers results in output power values of around 1.0 mW per fiber channel at low drive currents of only 150 mA.
The low-loss optical architecture in forward and backward direction offers power-efficient operation with low SLED drive currents and thus low TEC currents over the full temperature range from -40°C to +85°C.
Thanks to the micro-optical integration of the three closed-loop FOGs, the 14-pin BTF module, allows the creation of products with a less external components and a significantly reduced footprint.
“I always look forward to the Prism Awards ceremony,” says SPIE CEO Kent Rochford. “These awards give us the opportunity to showcase and appreciate the impact that optics and photonics technologies have on our lives as well as the efforts required to bring them to market. It’s an honor to acknowledge the scientists, engineers, and companies working to solve problems with light, and I’m excited to congratulate all the finalists and winners at our celebration at Photonics West in January.”
