ABSTRACT:
Using polymeric dielectric materials (preferably materials derived from bisbenzocyclobutene monomers) and an electron beam lithography process for patterning this material, we have developed a process for fabricating optical waveguides with complex integrated devices such as gratings. Such gratings are not limited to one-dimensional type gratings but can include 2 dimensional gratings such as curved gratings or photonic crystals. Due to the properties of BCB, this process could also be implemented using optical photolithography depending upon the waveguide dimensions desired and the grating dimensions desired. Alternatively, the optical waveguide could be patterned using optical lithography and the grating can be patterned using electron beam lithography. In addition, the general process described below can be applied to the fabrication of complex lightwave circuits containing, for example, multiple optical waveguides, couplers/splitters, grating based filters and even more complex devices and structures.
