Abstract
An arrayed-waveguide grating multiplexer with thin-film heaters is fab ricated to compensate for phase errors in arrayed waveguides. The phas e errors are measured by Fourier transform spectroscopy with a low-coh erence interferometer and are used as a monitor when we adjust the pha ses by controlling thin-film heaters. A channel crosstalk of -25dB and a loss of 4.2dB are achieved in a 5x5 10GHz-spaced multiplexer.
