In this paper, we provide a simple but powerful module to generate entangled qudits. This module, assisted with cross-Kerr nonlinearity, is flexible for generation of entangled qudits with arbitrary dimensions. Since the generation is still probabilistic, we modify the simple module in order to increase efficiency and save resources. With the modified module, the input independent qudits could be transformed into different entangled forms, which include the possible maximal entangled form and the less entangled forms. The corresponding total success probability could reach 1.
