    Organic Optical Upconversion Offers Alternative to InGaAs-Based SWIR Imaging

    Article obtained from Photonics RSS Feed.

    A device constructed from low-cost materials and that exhibited high stability at temperatures as high as 392 °F (200 °C) is capable of imaging lightwaves in the shortwave infrared (SWIR) region. Scientists in Europe developed the organic (using components made from carbon) device by combining a squaraine dye-coated flexible substrate with an OLED.

    In application, when the dye absorbed SWIR waves, generating an electric current, the OLED converted the current into a visible image.

    The human eye is unable to image in the SWIR region, and while certain cameras can capture images of objects that reflect SWIR waves, those cameras can be expensive to manufacture. They are also made from inorganic components (semiconductor…
