We review the most important techniques to build logic devices in photonic crystals. In particular, we evaluated several papers that include different approaches such as self-collimation effects, multi-mode interference, waveguide intersection path and nonlinear effects. We then exploited the advantages and weakness of each method. With the resulting information, we addressed the main challenges and possible applications for each scheme. With this review we expect to improve the development of PhC integrated logic devices and circuits.
