    Abstract: Prism-coupling systems and methods for characterizing large depth-of-layer waveguides formed in glass substrates are disclosed. One method includes making a first measurement after a first ion-exchange process that forms a deep region and then performing a second measurement after a second ion-exchange process that forms a shallow region. Light-blocking features are arranged relative to the prism to produce a mode spectrum where the contrast of the mode lines for the strongly coupled low-order modes is improved at the expense of loss of resolution for measuring characteristics of the shallow region. Standard techniques for determining the compressive stress, the depth of layer or the tensile strength of the shallow region are then employed. A second measurement can be made using a near-IR wavelength to measure characteristics of the deeper, first ion-exchange process. Systems and methods of measuring ion-exchanged samples using shape control are also disclosed.

    Abstract: Measurements are made on a sample (1) to obtain an experimental profile (2) having structural features (3, 4) determined at least in part by the given characteristic and an expected profile (5) calculated for the sample using selected parameters. A degree of smoothing is applied to the experimental profile (2) to reduce the structural features (3,4) thereby producing a smoothed experimental profile (21 a) and the same degree of smoothing is applied to the calculated profile (5) to produce a smoothed calculated profile 51 a. The smoothed calculated profile (51 a) is compared with the smoothed experimental profile (21 a) to determine the difference between the smoothed profiles. The calculated profile is then modified by varying at least one of the parameters until the smoothed modified profile fits the smoothed experimental profile. The above steps are then repeated with the modified calculated profile using each time a degree of smoothing less than the previous time so that the structural features return and the final modified calculated profile (5b) provides a desired fit to the experimental profile (2) thereby enabling the given characteristic to be determined from the parameters used for the final modified profile.
