Light-guiding thin films of various materials have been deposited on glass substrates from liquid solutions by slow evaporation of the solvent. The attenuation of the guided light wave in some of these films is as low as that in the best films prepared by other methods. Film deposition from solution is done at or near room temperature. Therefore, this technique allows us to dope the thin films with organic molecules, e.g., laser dyes. The preparation and light-guiding properties of the doped and undoped films are described. The materials studied were epoxy, lead-silica, polyurethane, and Kodak photoresist KPR. Films of the first and second material have shown losses as low as 0.3 dB/cm at wavelengths of 0.633 μm and 1.064 μm, respectively. Films of polyurethane have been prepared with rhodamine 6G doping. When pumped with a pulsed nitrogen laser, the doped films showed optical gains of up to 100 dB/cm. The KPR films have an attenuation of ~1 dB/cm at 1.064 μm. This low optical loss, in combination with the photographic sensitivity of the KPR, offers the possibility of fabricating integrated optical circuits directly in the photoresist films.

We did not investigate this material further despite its reportedly better resolution, because we found its attenuation at λ = 0.633 μm to be high (of the order of 500 dB/cm). At λ = 1.06 μm, however, the attenuation is only ~1.6 dB/cm. [CrossRef]
