Photonic integration of PHASARS with active compoments will provide the functionality required in tomorrows m ulti-wavelength networks. SUMMMARY Commercial interest in multi-wavelength components and systems is rapidly increasing. WDM provides a new dimension for solving capacity and flexibility problems in the telecommunication network. It offers a huge transmission capacity and allows for novel network architectures which offer much more flexibility than the current networks [ 1,2]. Multi- wavelength links and networks require optical components with an increased functionality, such as multi wavelength (MW) receivers, MW-sources, add-drop multiplexers and optical cross connects. A key component in MW-devices and circuits is the wavelength (de)multiplexer. Phased array (PHASAR) demultiplexers have proven to be robust components [3] which are particularly suitable for integration with other components. Integration with detectors in MW-receivers [4,5], with optical amplifiers in MW-lasers [6,7] and with optical switches in MW-add-drop multiplexers [8,9] has been reported. Photonic integration offers the potential to provide the functionality required in future MW- networks in a compact way. Performance and fabrication issues of integrated PHASAR-based devices will be discussed. References. C.A.
