Idealphotonics' 1200-1350nm VCSEL diodes are short-wavelength infrared vertical-cavity surface-emitting lasers based on the InP/GaAs material system. They achieve long-wavelength emission using novel InGaAsP/InP quantum wells or GaAsSbN structures, primarily for specialized applications such as 1310nm optical communication, gas sensing, and medical imaging. These diodes are key devices filling the gap in traditional near-infrared and mid-infrared laser technologies.The short-wavelength infrared emission achieved through InP/GaAs heterojunction technology overcomes the wavelength limitations of traditional materials, exhibiting unique spectral matching advantages in specialized applications such as 1310nm optical communication, methane detection (1330nm), and biological tissue imaging. However, they also face key technical challenges such as insufficient DBR reflectivity and high-temperature stability.
