Embodiments of a glass laminate structure comprising a non-strengthened glass sheet, a strengthened glass sheet, and at least one polymer interlayer intermediate the external and internal glass sheets are disclosed. The strengthened glass sheet can have a thickness ranging from about 0.3 mm to about 1.5 mm, the non-strengthened glass sheet can have a thickness ranging from about 1.5 mm to about 3.0 mm, and the polymer interlayer can have a first edge with a first thickness and a second edge opposite the first edge with a second thickness greater than the first thickness. The glass laminate structures provide advantageous optical properties. The glass laminate structure can be employed to provide a transparent display screen that minimizes image offset between two images formed by two reflections at two surfaces of the strengthened internal glass sheet.

Glass laminate structures for head-up display system

A method of measuring the shape of a glass sheet is provided. The method includes positioning the glass sheet in contact with a fluid and measuring the distance between a sensor and a surface of the glass sheet at a plurality of locations on the surface thereof. The method may further include deconvolving the shape of the glass sheet into at least one simple shape element, such as cylindrical or spherical, and may further include varying the temperature profile of an array of heaters in a glass manufacturing process based on the at least one shape element.

Phosphorus-silicate fibers suitable for extended band amplification

Disclosed are optical gain fibers which include an erbium-containing core and a cladding surrounding the core and which have ripple of less than about 25% over about a 40 nm wide window or ripple of less than about 15% over about a 32 nm wide window, or both. In one embodiment, the optical gain fibers are pumpable at 980 nm and at 1480 nm. In another embodiment, the optical gain fibers are fusion sliceable. In yet another embodiment, the core includes oxides erbium; the cladding includes silicon dioxide; and the optical gain fiber has a passive loss of less than about 0.5% of the peak absorption of the erbium absorption band in the vicinity of 1530 nm. The optical gain fibers of the present invention have a wider gain window, improved flatness across the gain window, and/or increased gain as compared to conventional optical gain fibers. Accordingly, they are useful in amplifying optical signals, particularly signals which need to be repeatedly amplified over the course of a long-haul transmission, without losses in the signal quality that are commonly encountered in conventional optical signal amplifying methods.
