Achieving high sensitivity and fast response simultaneously! High-speed photodiode compatible with blue-violet lasers.
At Corden, we have developed a new silicon photodetector using our unique technology. This newly developed photodetector achieves both high sensitivity and fast response simultaneously, and it also has high stability against blue-violet laser light. It is being mass-produced as the blue-violet compatible high-speed diode "PDZ702NB."

Company information
1. Optical Sensing Related Optical sensors have a proven track record with major home appliance and industrial equipment manufacturers as core products, and we are advancing the development of optical, circuit, and mechanical designs to meet diverse sensing requirements. We are developing mixed-signal ICs that incorporate digital processing circuits, leveraging the features of fine sensing through 3D processing and sub-micron C-MOS wafer processes, resulting in compact, high-performance, high-value-added products. 2. Optical Media Related We have a wide range of products and a proven track record in CD/DVD technology. In response to market demands for high-speed and short-wavelength applications such as Next DVD, we are advancing the development of dedicated epitaxial equipment and processes for miniaturization. We plan to ship sample products of silicon photodetectors that utilize the quantum effects of ZnO/Si heterojunctions, which exhibit blue sensitivity and high-speed performance.
