摘要：
This study demonstrates the use of photonic crystal directional couplers to separate light of wavelengths 1.31 and 1.55mum. The photonic crystal structure consists of InAlGaAs nano-rods arranged in square lattice. The coupling length of the light in the directional coupler at a wavelength of 1.31mum was designed to be four times greater than that at 1.55mum. This behavior helps in designing devices to split the two wavelengths. The devices are fabricated by e-beam lithography and conventional photolithography. The measurement results confirm that 1.31mum/1.55mum directional couplers can be realized in PC structures formed by nano-rods. (C) 2005 Optical Society of America.
