Abstract
The operating principle of our polarization mode splitter is based on the polarization-dependent refractive index changes induced by disorde ring InGaAs/InP superlattices. We disordered superlattices by the Si3N 4 cap-annealing method and measured the near-field patterns to confirm that the device functioned properly at a wavelength of 1.52 mum. The crosstalk was about -10 dB. We should be able to improve the character istics of this device by optimizing its structure. This device require s no electrical control and will be very suitable for semiconductor mo nolithic integrated circuits.
