The silver sodium ion exchange process is a versatile and flexible technique for realizing high quality refractive microoptical elements with a high degree of freedom in design. An accurate mask technique allows for implementing a huge variety of opt

We present the semi cylindrical H-ROD elements as a new and versatile microoptical component. With field assisted ion exchange semi cylindical index distributions can be integrated in a planar glass substrate. By combination of two identical elements

We report the fabrication of planar microlenses with numerical apertures (N.A.’s) of 0.2 by field-assisted Ag–Na ion exchange in glass. To measure the N.A. of microlenses, different definitions can be used. We discuss the issue of measuring the N

It is shown that a hemispherical-rod microlens can act as a fractional Fourier transform device with a continuously varying degree of fractionality. It is believed to be the first proposed device to perform such a task; its most immediate application

The interconnection system proposed here, utilizes D-shaped multimode waveguide structures, which are embedded in a planar substrate. The flat side of the D-structure is realized as the substrate surface. In analogy to D-fibers we will use the expres

We proposed a method for designing arbitrary two -dimensional continuous phase elements. With this method, phase anomalies due to amplitude zeros can be avoided completely. Fabricated examples using direct write in resist and also ion exchange are pr

A new concept for a common interface between passive and active single-mode devices is proposed. The submicrometer alignment accuracy necessary for efficient coupling of single-mode devices is extended to the range of some 10 µm by beam expansion wi

The phase-space measurement of micro-optical objects with submillimeter dimensions is reported for the first time to our knowledge. The experimental data were compared with simulated results from interferometric measurements and were found to be in g

Fabrication of planar microlens arrays by silver-sodium ion exchange is possible by using a new glass type, optimized for this technology. Because of its nonlinear diffusion response it is well suited to the fabrication of microlens arrays. We show t
