ABSTRACT:
Optical communication apparatus for simultaneously and reconfigurably establishing optical communication channels, comprises at least one light source and a plurality of wavelength-selective detectors optically associated with each light source, the detectors arranged one behind another. The apparatus uses wavelength-division-multiplexing (WDM) to facilitate simultaneous and reconfigurable communication of one-to-many 2-D optical planes. This advance dramatically increases the system functionality of optical-plane interconnects. Such a system is realized by incorporating several multiple wavelength vertical-cavity surface-emitting lasers (VCSEL) into each transmitting pixel and incorporating wavelength selectivity into each subsequent detecting plane which will absorb one wavelength and be transparent to the rest; these structures can be fabricated by slightly modifying existing technology. This system allows for increased processing functionality of communicating both simultaneously and reconfigurably between many planes; broadcasting and dynamic independent interconnects are thus enabled.
