Paper Abstract

We present a thirteen-channel infrared wavelength division demultiplexer based on multiplexed phase-matched volume holograms recorded in a graded index (GRIN) polymer thin film waveguide. Channel center wavelengths ranged from 844 to 976 nm (11 nm channel separation), with corresponding output diffraction angles of 22 degree(s) to 70 degree(s) (4 degree(s) between channels). The device demonstrated diffraction efficiencies from 40% to 65% with an average channel crosstalk of -17.2 dB, which is largely attributable to the spectral width of the Ti:Al2O3 laser source. The optical power requirements of the system are evaluated and shown to be well within practical limits.
