Edinburgh Instruments Quantum dots, nanoscale semiconductors with unique optical properties, are revolutionising fields like biological sensing, display technologies, and photovoltaics. Researchers can delve deeper into their properties using a suite of imaging techniques, including Raman spectroscopy, photoluminescence (PL) spectroscopy, and fluorescence lifetime imaging microscopy (FLIM). The Edinburgh Instruments RMS1000 simplifies this process by enabling all imaging modes within the same software package on the same area or volume of a sample.

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. Thanks to the micro-optical integration of the three closed-loop FOGs, the innovative 14-pin BTF module, allows the creation of products with a less external components and a significantly reduced footprint.
