Paper Abstract

Highly efficient and good quality blazed diffraction gratings are required to achieve low insertion losses of wavelength division multiplexer/demultiplexer in multichannel multiplex systems. This paper presents a method and describes the technology for fabrication of diffraction gratings on glass using an ion etching technique. In contrast to other methods, ion etching technique allows not only the fabrication of arbitrary blaze angles but also different blaze angles can be realized on a single glass sample. The process is low in cost, uses readily available materials and has mass production capability.
