33. We have recently realized even lower loss values in partially halogenated materials (for example, 0.7 dB/ cm at 1300 nm and 1.0 dB/cm at 1550 nm).
34. Coupling losses of less than 1 dB have been realized by means of exploiting mode size matching techniques and vertical transition waveguide structures [S. M. Garner et al., IEEE J. Quantum Electron. 35, 1146 (1999)]. The total insertion loss of a commercial (Pacific Wave Industries, Los Angeles, CA) EO modulator based on the CLD-1 chromophore is comparable to that of the Lucent lithium niobate modulator.

39. As can be seen from Fig. 2, even modest modification of the structure of CLD-1 can lead to significant improvement in optical nonlinearity. A particularly attractive route to increasing conjugation length while maintaining exceptional thermal and photochemical stability is the insertion of dithiophene units I. Liakatas et al., Appl. Phys. Lett., 76, 1368 (2000); L R. Dalton et al., U.S. Patent pending.
