Abstract
An apparatus for coupling light from a laser chip into an unetched and uncoated optical fiber includes a substrate carrier having a V-groove extending axially through the substrate carrier. The fiber has a beveled end with an inner and outer face and is positionable in the plane of the laser chip within the V-groove such that light emitted by the laser chip strikes the inner face of the beveled end and is totally internally reflected into the fiber core.
