摘要：A semiconductor optical functional device is divided into two regions of a firstregion 1 and a second region 2 adjacent to each other in a longitudinal direction of asemiconductor optical waveguide. The first region 1 is provided with a region including an
MQW structure in which a compressive strain is introduced, and the second region 2 isprovided with a region including an MQW structure in which a tensile strain is introduced.Electrodes 3 and 4 formed separately and independently from each other arerespectively disposed on the first region 1 and the second region 2, and bias voltagesapplied to the electrodes 3 and 4 are adjusted so that transmissivities for light having aTE mode component and light having a TM mode component are independentlycontrolled.
