Broadband optical modulator of fiber type.
A novel lithium niobate optical modulator of fiber type is proposed. The velocity match and the impedance match can be achieved simultaneously. The modulator is analyzed and designed with the finite element method. The designed modulator operates with a low half-wave voltage of 2.28V, a broad 3dB optical bandwidth of 116.3GHz and a characteristic impedance of 50.67? at 1.5microm wavelength.
