Mid and Long Wavelength Infrared Photonics, Materials, and Devices

Mid and long wavelength infrared (MWIR/LWIR, ranging from 2 to 20 μm) materials and devices are in high demand across various fields, including biochemical sensing, thermal sensing and imaging, free space communication, spectroscopy, astronomy, defense and security, anticounterfeiting measures, medical diagnostics, and environmental pollution monitoring. However, despite their strategic significance, numerous challenges have impeded their advancement and widespread use. Overcoming these obstacles requires a substantial reduction in production costs, enhanced integration with control electronics, and a broader range of emitters, detectors, and optoelectronic devices. To address these challenges, the development of novel materials, innovative device designs, and more precise metrology tools is imperative.

This Special Topic Collection serves as a platform for discussing the latest advancements in MWIR/LWIR physics and technologies. The broad MWIR/LWIR communities are invited to publish the latest developments in all key areas related to MWIR/LWIR physics and engineering.
