  • Abstract
    The authors propose a practical optical path length trimming technique and demonstrate this using thin film heaters for silica based planar lightwave circuits (PLCs). Irreversible refractive index changes up to 1.5×10-4 can be obtained to trim the PLC response by simply controlling the heating power and time. This technique is applied successfully to thermo-optic switches to maximise their extinction ratios
