CONJUGATE ... BOND POLYMERS WITH ULTRASENSITIVE NONLINEARTIES AT 0.8 AND 1.3 MICRONS

PHYSICAL OPTICS CORPORATION (POC) PROPOSES TO DEVELOP A NEW HIGHLY CONJUGATED ORGANIC POLYMER WITH UNUSUALLY HIGH THIRD ORDER NONLINEARITY IN ORDER TO FULFILL THE CONDITION OF GIGAWATT/CM(2) LASER DAMAGE THRESHOLD AND MILLIWATT LEVEL SENSITIVITY AT 0.8 AND 1.3 MICRONS. POC'S INTERNAL RESEARCH INDICATES THAT SUCH A POLYMER CAN BE SYNTHESIZED FROM SUBSTITUTED IDANCINOSTYRENE AND CYANOGEN COPOLYMERIZATION. THE GOAL OF THIS RESEARCH IS TO FURTHER DEFINE AND INTEGRATE THE PREPARATIVE METHODOLOGY AND ENHANCE THE FIGURES OF MERIT TO ACHIEVE: (1) HIGH X(3), (2) MILLIWATT LEVEL SENSITIVITY AT 0.5 TO 3 MICRON REGION AND (3) FABRICATION FLEXIBILITY. POC'S NEW MATERIALS WILL BE FREE OF ABSORPTION DEPENDENT EXCITON OVERLAPPING AND RESONANCE SATURATION RESPONSIBLE FOR LOWERING THE NONLINEAR REFRACTIVE INDEX GENERALLY EXPERIENCE BY GAAS/ALGAAS MULTIPLE QUANTUM WELL STRUCTURES AT 0.8 AND 1.3 MICRON WAVELENGTHS. FURTHER, WAVEGUIDE/OPTICAL SWITCH WILL BE FABRICATED FROM THE COMPOSITE POLYMER TO DETERMINE IMPLANT SCATTERING, PHOTO REFRACTIVE (OPTICAL) DAMAGE AND PROPAGATION LOSSES INCLUDING VOLUME SCATTERING, ROUGHNESS AND ABSORPTION.
