ABSTRACT:
A connector assembly for coupling an optical fiber to an active optical device has a metal sleeve and an L-shaped alignment block having perpendicularly disposed reference surfaces. A resilient member on the sleeve biases an optical fiber terminating plug against the reference surfaces. The active optical device is attached to a ceramic sub-mount and the sub-mount is placed on one of the reference surfaces. The sub-mount is sized so that an optical port for the active optical device will become aligned with the central axis of the plug. To couple the optical fiber with the active optical device, the plug is slid into contact with the active optical device and is rotated until the fiber is substantially registered with the optical port. The sleeve may have a second resilient member for receiving another plug from the opposite end of the sleeve with a fiber in the other plug being coupled to a second optical port. The active optical device can comprise a variety of devices, such as a laser or an optical modulator with mode field beam expanders.
