According to recent market analysis, the global Metal-Semiconductor-Metal (MSM) Photodetector market was valued at USD 74 million in 2024 and is projected to reach USD 112 million by 2031, growing at a steady Compound Annual Growth Rate (CAGR) of 6.3% during the forecast period. This growth is fueled by increasing demand in optical communication systems, advancements in semiconductor technology, and the rising adoption of photonic integrated circuits across various industries.
What is a Metal-Semiconductor-Metal Photodetector?
Metal-Semiconductor-Metal (MSM) Photodetectors are optoelectronic devices that detect light by converting photons into electrical signals. They consist of interdigitated metal electrodes deposited on a semiconductor substrate. When photons strike the semiconductor material, they generate electron-hole pairs that create measurable current under an applied electric field.
These devices are particularly valued for their high-speed operation, low dark current, and compatibility with standard semiconductor fabrication processes. MSM photodetectors find extensive applications in optical fiber communications, light detection and ranging (LiDAR) systems, and various sensing applications where fast response times and reliability are critical.
