Abstract :
Summary form only given. In earlier work we have demonstrated a novel integrated optic approach to 10.6 micron coherent laser radar systems. The approach is based on locating all the required system components in alignment slots in a dielectric substrate. Laser radiation is guided between the components in hollow waveguides formed in the surface of the substrate. The hollow waveguides exhibit low loss as a consequence of anomalous dispersion phenomena. These are brought into play by appropriate choice of the substrate material. The waveguides are created in the surface of the substrate using computer controlled machining techniques. The approach leads to waveguide subsystems which have high power transmission, are very rugged and compact and have good coherent detection efficiencies.
