Abstract
We report the 1x4 optical splitters (OS's) for TE modes based on an air-hole type silicon photonic crystal selfcollimation (SC) effect ring resonator (SCRR). The OS has four beam splitters which are formed by changing the radii of the air holes. With the self-collimation effect and the radii we set for beam splitters, the light beam's propagation will be well controlled. Using the multiple-beam interference theory, we analyse the theoretical transmission spectra and make the simulation, which is realized by two-dimensional finite-difference time-domain (FDTD) simulation technique. As we expected, the results have a good agreement with the theoretical calculation Small-dimensions, low-loss of the OSs will have an important role in photonic integrated circuits in the future.
