摘要
A planar lightwave circuit comprises a waveguide that is thermally-compensating. The waveguide comprises a cladding and a core that comprises two regions running lengthwise through the core. One region has a negative thermo-optic coefficient; the other region has a positive thermo-optic coefficient.
