    摘要： A leaky plasmon mode directional coupler and a polarization detection module for a magneto-optical pickup head, which uses the leaky plasmon mode directional coupler, are provided. The leaky plasmon mode directional coupler is manufactured by integrating a planar waveguide and a leaky plasmon mode waveguide, which share a cladding layer with each other, into one body. The polarization detection module includes the leaky plasmon mode directional coupler, a first photo diode, which is formed on the leaky plasmon mode directional coupler, and a second photo diode, which is located at an output port of the planar waveguide.
