Silicon Optical Modulators for Data Transmission in Different Wavelength Bands

High-speed and low-power silicon optical modulators are key in realising low cost photonic circuits for data transmission purposes. Depending on the application, different wavelength bands are preferred and therefore designs of optical modulator, which operate in these bands, are required. Here we present our recent work on silicon optical modulators at 1310, 1550, 2000 and 3800 nm wavelengths.
