Abstract
An electrical-optical coupling device. An apparatus according to an embodiment of the present invention includes a first trench defined in a first semiconductor substrate. A first reflector is defined at a first end of the first trench in the first semiconductor substrate. The first reflector is angled with respect to an axis of the first trench. A first optical fiber is disposed in the first trench at a second end of the first trench. An optical source is mounted to the first semiconductor substrate proximate to the first trench. The optical source is optically coupled to the first optical fiber via the first reflector.
