The paper reports 13 and 12 photonic drop splitters (PDSs) for TE modes in a silicon photonic crystal based on self-collimation effect. The 13 PDS consists of four beam splitters and the 12 PDS consists of three beam splitters and one mirror. The theoretical transmission spectra at different drop ports in PDSs were analyzed with the multiple-beam interference theory. The PDSs with different splitting ratios can be designed by selecting beam splitters appropriately. For the 13 photonic drop splitter, we designed two splitting ratios of 1∶1∶1 and 1∶2∶3. For the 12 photonic drop splitter, we designed two splitting ratios of 1∶1 and 1∶2. Then the performances of the PDSs were investigated with the finite-difference time-domain (FDTD) simulation technique, whose results agree well with theoretical predictions. For the drop wavelength of 1550 nm, the dimensions of the PDSs are about 10 m10 m, and the free spectral range are about 36 nm, which almost covers the whole optical communication C-band window.
