The design,fabrication and characterization of a fundamental/first-order mode converter based on multimode interference coupler on InP substrate were reported.Detailed optimization of the device parameters were investigated using 3D beam propagation method.In the experiments,the fabricated mode converter realized mode conversion from the fundamental mode to the first-order mode in the wavelength range of 1530-1565 nm with excess loss less than 3 dB.Moreover,LP_(01) and LP_(11) fiber modes were successfully excited from a few-mode fiber by using the device.This InP-based mode converter can be a possible candidate for integrated transceivers for future mode-division multiplexing system.

The experiments, the fabricated mode converter realized mode conversion from the fundamental mode to the first-order mode in the wavelength range of 1530-1565 nm with excess loss less than 3 dB. Moreover, LP_ (01) and LP_ (11) fiber modes were successfully excited from a few-mode fiber by using the device. This InP-based mode converter can be a possible candidate for integrated transceivers for future mode-division multiplexing system.
