A model for describing the operation of an integrated electrooptical polarization controller on LiNbO/sub 3/ as a function of the applied voltages is presented. This model contains several parameters; for their determination, a special measurement pr

A theoretical method is described from which the thickness of an arbitrary layer in a dielectric multilayer stack is determined if all other thicknesses and all refractive indices are given, such that a prescribed effective index for a given mode of

An integrated optical interferometer consisting of Al(2)O(3) waveguides placed upon an oxidized Si substrate is presented. The two waveguides forming the branches of the interferometer are stacked on top of each other with a SiO(2) buffer layer in be

The paper describes an interferometer for use in the thickness determination of optical thin films. The standard deviation obtained by repeated measurements is of the order of 0.3 nm. In those measurements, the thickness is obtained as a fraction of

We present a new finishing process that is capable of locally shaping and polishing optical surfaces of complex shapes. A fluid jet system is used to guide a premixed slurry at pressures less than 6 bars to the optical surface. We used a slurry compr

The imaging properties of a real-time shearing interferometer are presented. The use of Savart elements, both as a beam displacer and an analyzer in a polarization phase-stepping scheme, is demonstrated in a real-time, two-camera, four-bucket shearin

In this paper, a new finishing process, Fluid Jet Polishing (FJP), is presented that is capable of locally shaping and polishing complicated optical surfaces in brittle materials (e.g. glass). Within FJP, a fluid jet system is used to guide a premixe

The generation of off-axis parts of rotationally symmetric surfaces applying FAUST and WAGNER is analyzed showing that there are often two fabrication processes possible. The producible surface shapes are discussed showing the possibility of producin

A new fabrication technique, derived from an earlier development to produce on- and off-axis optical surfaces of revolution is presented. Although based on a shape copying method, it is possible to generate different types of surfaces with the same m
