Polymeric phased array wavelength multiplexer operating around 1550 nm

A polymeric, optical fibre compatible, 8/spl times/8 phased array wavelength multiplexer with 400 GHz (3.2 nm) channel spacing, has been designed and realised for operation in the 1550 nm erbium doped fibre amplifier (EDFA) window. By using bending radii as small as 20 mm, the device measures only 64/spl times/4 mm. The fibre to fibre insertion loss in the passbands varies between 6.6 and 8.0 dB and the crosstalk is -25 dB.
