Paper Abstract

In this paper, we propose and experimentally demonstrate the principle of a novel reconfigurable optical add-drop multiplexer (ROADM) structure employing an Opto-VLSI processor. The ROADM structure integrates two arrayed waveguide gratings for wavelength division multiplexing and demultiplexing, a 4-f imaging system comprising a fiber array, an imaging lens array and a reflective Opto-VLSI processor. The Opto-VLSI processor is driven by phase holograms to switch the various wavelength channels between the fiber ports to achieve "through" or "drop" operations. Phase hologram optimization is investigated, for maximising the number of wavelength channels while keeping adequate insertion loss and crosstalk levels. Experimental results are shown, which demonstrate the principle of the ROADM with crosstalk of less than -30dB and insertion loss of less than 6dB for the drop and through operation modes.
