“…Bimodal behavior, checked by the CCD camera, appears for waveguides with diffusion aperture wider than 4 μm. This figure shows that the birefringence increases with the width of the waveguide diffusion aperture, as already reported in [9].…”

This paper deals with an experimental nondestructive technique for the measurement of modal birefringence of integrated optical waveguides. The method is based on a magnetooptical perturbation technique combined with a highly sensitive polarimeter. Magneto-optical modal conversion, through the Verdet constant of the waveguides, and its dependence on the perturbation length are discussed. In this paper, the practical application of this equipment is proposed for the measurement of modal birefringence in totally or partially buried ion exchanged waveguides.

“…The waveguides were fabricated into BGG31 glass by molten salt ion exchange followed by a burial process [9,10]. Aluminoborosilicate glass BGG31 was specifically developed to fulfill the requirements of ion-exchanged waveguides in passive (i.e., undoped) glass [11].…”

In this paper, we review our recent work on exploring and developing new techniques for planar lightwave circuits utilizing silver-sodium ion exchange. In the experiments, two special kinds of glass substrates have been used: aluminoborosilicate glass (also called BGG31) specially developed for passive ion-exchanged waveguides and phosphate glass (commercial name IOG-1) designed for waveguide laser applications. Phosphate glass can be doped with large amounts of rare earth ions without significant lifetime reduction. This enables fabrication of short-cavity waveguide lasers, a desirable feature for example in high-repetition rate modelocked lasers operating at 1550 nm wavelength region. Birefringence properties of buried molten salt ion-exchanged waveguides in BGG31 glass are presented in detail. Photosensitivity properties of both undoped and Er-Yb-codoped IOG-1 glass are discussed. A new approach to fabricate waveguide Bragg gratings through UV exposure in IOG-1 glass will be presented.

“…9 We have recently shown that the fundamental mode of ion-exchanged waveguides can have very low birefringence for waveguides with widely varying widths. 10 Values of the order of 10 Ϫ6 were measured when the burial process was followed by thermal annealing. However, we were not able to measure the birefringence for the odd mode and no waveguide grating was included.…”

Polarization dependence of UV-written Bragg gratings in buried ion-exchanged glass waveguides is investigated. A polarization-dependent shift in Bragg wavelength of less than 0.02 nm is measured, both for the even and the odd modes of a laterally dual-mode waveguide. The measured wavelength shift corresponds to a waveguide birefringence of the order of 10(-5), which is negligible for most applications in optical communications. It is observed that the UV-induced birefringence is small, within the limits of the measurement accuracy. The thermal stability of the fabricated gratings is also very good. The results are of particular importance for devices considered here since they require a polarization-independent mode-converting waveguide Bragg grating. Polarization-independent performance of these gratings enables the fabrication of a new class of integrated optical devices for telecommunication applications.
