Polarization crosstalk in planar lightwave circuit directional couplers can cause significant polarization-dependence in interferometers that use them. We show a simple way to mitigate the polarization crosstalk without incurring a performance penalty or requiring extra fabrication steps. We demonstrate it on a 23-ps Mach-Zehnder delay interferometer
We integrate an improved colorless thermooptic-lens-based tunable dispersion compensator (tuning range of plusmn160 ps/nm) with a tunable amplified spontaneous emission filter on a single silica waveguide chip. We demonstrate fast automatic adjustment of the compensator
