Abstract

We have developed effective techniques for the design and fabrication of large and complex integrated optical components in lithium niobate. The application of these techniques to the design of an 8x8 space switch array suitable for switching broadband traffic in an optical fibre network is discussed. We consider system constraints on wavelength, loss and crosstalk. The implications of using different switch architectures both on the chip and when interconnecting multiple chips to form larger switch networks are studied. The design of the component has been optimised within the constraints of the integrated optical technology and the packaging and interconnection of the device, taking the system requirements fully into account. Flexible techniques for mask coding and mask production are described. We have measured fully functional switch arrays with switching voltages of 25V and optical loss of 5.5dB.
