A tunable optical 90°hybrid composed of a 2 ×4 multimode interference (MMI), a 2 ×2 MMI coupler and a heater pad is proposed, and a set of formulas was deduced for calculation the light intensity output of the device. The simulation has been performed, and the results show agreement with analytical predication. In the wavelength range of c band, the imbalances are below 0.04dB, the excess loss is less than 0.45 dB, and the phase deviations are below 3°. The fabrication tolerance of width as high as 0.3μm, which i...
