SWIR sensors

 

SWIR sensors provide clear visual data even in low light, detecting both reflected and emitted IR light. These sensors use semiconductors to convert light signals into electrical signals. SWIR sensors often use compound semiconductors, which have better electron mobility than silicon. This allows them to detect faint light signals efficiently.

Researchers developed a new compound semiconductor material to improve SWIR sensing. They tackled issues such as high production costs and lattice mismatch with indium gallium arsenide (InGaAs). The team developed indium arsenide phosphide (InAsP), which offers better performance, lower noise, and a wider detection range.

To reduce material mismatches, the researchers used a special layer that allowed for flexible adjustments. They also developed high-quality LEDs that work efficiently and remain stable, even in high heat. These LEDs maintain their performance with little loss and stable light output.

The new InAsP material could benefit industries like life science, optical communications, and medical diagnostics, making it a crucial development in SWIR technology.
