Multi-wavelength fiber-optic processors based on a fault-tolerant scheme using a macro-pixel to control an optical beam are described. The macro-pixel system uses multiple device pixels per beam to provide a robust digital technique for amplitude control and routing, enabling a module with high optical...http://www.google.com.au/patents/US6859578?utm_source=gb-gplus-sharePatent US6859578 - Fault-tolerant fiber-optical multiwavelength processor
