Abstract :
Utilizing a recently developed novel two-step fabrication process we present the first experimental demonstration of photonic band-gap waveguiding structures inscribed into bulk optical glass via the femtosecond laser direct-write technique. The waveguides are fabricated by placing an array of circular high-index contrast rods around an unmodified core. We observe the formation of discrete band-gaps that can be precisely tuned by controlling the diameter of the individual rods.
