Abstract :
We present transmission spectra through a double-60° bend channel defined in a two-dimensional photonic crystal. The structures are patterned into a GaInAsP confining layer on InP substrate. Improved design of the corner allows to reduce losses down to 2dB for a micrometer long 60° bend.
