Semiconductor devices utilizing the mechanism of converting electric current into light
LEDs (light-emitting diodes) are semiconductor devices that convert electrical current into light. The color (wavelength) emitted is determined by the materials used in their construction. We handle LEDs across a wide spectrum of colors (wavelengths), including ultraviolet, visible light, and infrared. LEDs are characterized by their long lifespan and low power consumption, making them suitable for applications such as sensing when combined with photodetectors, and for lighting.

A light-receiving element that converts the intensity of incident light into an electric current
A photodiode is a light-sensitive device that converts the intensity of incident light into an electric current. The wavelength range and sensitivity it detects vary depending on the material used to construct the semiconductor device. When the material is silicon (Si), it is sensitive to wavelengths in the ultraviolet, visible light, and infrared (up to 1100 nm) ranges. When the material is a compound semiconductor such as InGaAs, it is sensitive to longer-wavelength infrared regions. By combining them with light sources, they can be used for various sensing applications.
