A SiGe electro-optic modulator operating at wavelength of 1.55 microm is proposed. The "ON" state voltage is set at 1.4V. The arm of the MZI waveguide required to generate a pi phase shift is 73.6 microm, and the total attenuation loss is 3.95 dB. The rise and fall delay time is 70.9 ps and 24.5 ps, respectively.
Electrically controlled wavelength switchable terahertz band pass filter based on photonic crystal structures with LC defect layer is proposed and discussed. The wavelength switching can be realized by reorienting liquid crystal molecules through adjusting the applied electric field. Numerical analyses results have shown that the proposed structure has the(More)
