Abstract
Abstract An optical module which can reduce its size, and a method of making the same are provided. The optical module has a substrate, a carbon-coated optical fiber, a ferrule, and an optical device. The substrate has first, second, and third regions along an axis, and also has a ferrule support groove in the first region, an optical fiber support groove in the second region, and a device mount portion in the third region. The carbon-coated optical fiber is mounted in the optical fiber support groove. The ferrule covers the side face of the optical fiber and is secured to the ferrule support groove. The optical device is mounted at the device mount portion and is optically coupled to the carbon-coated optical fiber.
