Small-form factor Reflective Integrated Silicon-based Slot-Blocker

We propose novel cost efficient node architecture for wavelength division multiplexed packet-switched network based on reflective integrated device. We demonstrate a 16- channel, silicon-on-insulator, reflective monolithic integrated slot-blocker that integrates two arrayed waveguide gratings, 16 variable optical attenuators, 16 Bragg grating mirror and one vertical fiber coupler. Small-form factor device, improved ER and fast switching speed are presented.
