Abstract :
Wavelength multiplexers produced using the fused taper technique have been fabricated to be insensitive to variations in the external refractive index, allowing them to be potted in silicone for environmental protection. The technique exploits two opposing dependencies by fabrication at a particular coupler cross-section
