Abstract : The objectives of this work were to develop devices for optical interconnects in the mid-IR, develop devices for mid-IR ranging, IR decoy projection, free space communication, pollution monitoring, and digital optical logic. In addition,it was desired to three dimensional opto-electronic systems with very large scale integrated optics with ultra high confinement waveguides. Advances included the use of quantum wells in the electrode to reduce free electron absorption; use of electrode resonances in the far-IR to reduce penetration of mid-IR light; and use of step wells and dope in barrier to lower linewidth and increase separation of states.
