Fabrication of Polymeric Multimode Waveguides and Devices in SU-8 Photoresist Using Selective Polymerization.

Large cross section multimode waveguides have been realized in SU-8 using selective polymerization. SU-8 is a negative photoresist, which has shown good optical properties and it is mechanically and chemically stable. The fabricated waveguides have very smooth sidewalls and exhibit low optical losses. The fabrication method is simple and potentially very cost effective. N x N and 1 x N multimode power splitters have been realized using this fabrication technology

Completely multimode arrayed waveguide grating-based wavelength demultiplexer

A multimode fiber-matched arrayed waveguide grating-based demultiplexer has been demonstrated. In this design, multimode waveguides have been used as array elements. The device, which can be used in short-distance communications, has been realized using low-cost polymer planar waveguide technology. Three wavelength channels were successfully separated. The average fiber-to-fiber insertion loss was 14 dB and the worst-case cross talk was < -12.5 dB
