TOKYO–(BUSINESS WIRE)–Using silicon photonics technology for semiconductor optical circuits, OKI (TOKYO: 6703) has successfully developed an ultracompact photonic integrated circuit chip with a broad range of potential applications, including optical fiber sensors, laser vibrometers, and optical biosensors. This makes it possible to achieve ultra-miniaturization and low power consumption similar to LSI (Note 1), as well as dramatically lower costs through mass production of optical sensor modules. Optical sensors are a technology that uses optical fibers and…
