摘要：

We demonstrate a UV-written polymer long-period waveguide grating (LPWG) coupler, which offers a bandwidth of similar to 20 nm, a maximum coupling efficiency of similar to 80% and similar to 60% for the TE and TM polarizations, respectively, and a wavelength-tuning range over the (S + C + L)-band (similar to 140 nm) with a temperature control of similar to 25 degrees C. The LPWG coupler has the potential to be developed into a practical broadband add/drop multiplexer for coarse wavelength-division-multiplexing applications. (C) 2008 Elsevier B.V.
