Abstract :
Successful athermalisation of a silica arrayed waveguide grating (AWG) multiplexer using compensating longitudinal strain is reported. Peak wavelength shift of <0.04 nm is recorded over 5-70°C in a 40×100 GHz device, representing a 95% reduction on standard silica AWGs, without introduction of birefringence or compromise of optical crosstalk.
