We experimentally confirmed the stability of a zirconium-doped silica-based planar lightwave circuit, resisting refractive index changes after 2000 hours with over 30 milliwatts of blue-light input. For RGB coupler use, we expected that the PLC can output medium power (about 65 milliwatts) of blue-light power for 10,000 hours.
