Transmission measurement of tapered single-line defect photonic crystal waveguides

Two-dimensional tapered single-line defect photonic crystal (PC) waveguides were fabricated with coupled ridge waveguides in InP-InGaAsP and optical transmission characteristics measured. Three different taper designs that optimized both mode size match and impedance match between the accessing ridg...

Zusammenfassung:Two-dimensional tapered single-line defect photonic crystal (PC) waveguides were fabricated with coupled ridge waveguides in InP-InGaAsP and optical transmission characteristics measured. Three different taper designs that optimized both mode size match and impedance match between the accessing ridge waveguides and the PC waveguides were fabricated and characterized. An /spl sim/8-dB improvement of coupling efficiency was observed for the tapered structures over untapered.
