Abstract

A fully packaged dense wavelength division demultiplexer by using dispersion-enhanced volume holographic grating and V- grooved silicon fiber array is demonstrated. The device demultiplexes eight optical channels, namely at wavelengths of 1549 nm to 1536 nm every 2 nm respectively. The system insertion losses are -5.68 dB, -5.6 dB, -5.3 dB, -5.68 dB, -5.59 dB, -5.58 dB, -5.49 dB respectively. Typical adjacent cross-talks among these eight channels are less than -35dB. Epoxy and UV curing are used for fixing most parts of the optical components, which ensures the low cost of the devices. The trade-offs between getting smaller physical packaging size and linear dispersion ability at different wavelength is addressed.
