Light cannot be strongly confined in two-dimensional (2D) slab photonic crystal waveguides (PCWs) when the slab thickness is less than half a wavelength. By using the finite-difference time-domain method, we theoretically demonstrate that two metal plates clad 2D PCWs (MCPCWs) constructed by sandwiching a PCW into two parallel metal plates can well compress light field in the vertical direction of PCW plane. A method for improving the propagation efficiency of MCPCWs is suggested and demonstrated numerically. Our result implies that MCPCWs may provide another method to create planar PC devices on metallic surfaces for highly integrated optical circuits.
