摘要：

We first experimentally demonstrated ultra-compact four-channel drop filters based on one-dimensional photonic crystal nanocavities. The drop wavelengths were controlled at 7.9+/-0.3nm spacing by changing the cavity length of the nanobeam cavities on several nanometers. The device size was as small as 7 mu m x 34 mu m, and the extinction ratio was as high as 25dB.
