H-ROD: A new and versatile microoptical component
Abstract: We present the semi cylindrical H-ROD element as a new and versatile microoptical component. With field assisted ion exchange semi cylindrical index distributions can be integrated in a planar glass substrate. By combination of two identical elements an integrated GRIN ROD lens can be realized. Furthermore a semi cylindrical element can also be utilized for imaging by using internal reflection (H-ROD). Aside of this the H-ROD provides direct access to the filter plane, which offers a wide range of applications.
