DENDRITIC TAPER FOR AN INTEGRATED OPTICAL WAVELENGTH ROUTER

摘要

The present invention generally provides an optical wavelength router that includes at least one dendritic taper region (104). The dendritic taper region includes at least one dendritic taper which has a trunk (128) and at least one branch optically coupled to the trunk. In addition to the dendritic taper region, the optical wavelength router includes at least one input waveguide (102), a input slab waveguide (106), an arrayed waveguide grating (108), an output slab waveguide (110), and at least one output waveguide (114). The improved optical wavelength router provides a wide passband width without a substantial effect on insertion loss.
