Abstract: An optical interconnect device and the method of fabricating it are described. The device includes an in-plane laser cavity transmitting a light beam along a first direction, a Franz Keldysh (FK) optical modulator transmitting the light beam along the first direction, a mode-transfer module including a tapered structure disposed after the FK optical modulator along the first direction to enlarge the spot size of the light beam to match an external optical fiber and a universal coupler controlling the light direction. The tapered structure can be made linear or non-linear along the first direction. The universal coupler passes the laser light to an in-plane external optical fiber if the fiber is placed along the first direction, or it is a vertical coupler in the case that the external optical fiber is placed perpendicularly to the substrate surface. The coupler is coated with highly reflective material.
