摘要:

We have observed nonlinear absorption in spin‐coated poly(4,6‐decadiyne‐1, 10‐diolbis {[(n‐butoxycarbonyl)methyl]urethane}) [poly(3BCMU)] polydiacetylene channel waveguides at different wavelengths in the near‐infrared. Intensity dependent absorption coefficients, &agr;2and &agr;3, have been determined by measurements of the intensity dependent transmission. The implications of nonlinear absorption for all‐optical device applications in this material are discussed. ©1995 American Institute of Physics.
