Ultrasmall optical add-drop multiplexers (OADMs) with Si-wire waveguides were demonstrated. Bragg grating reflectors based on Si-wire waveguides were developed and used as the wavelength-selective mechanism in the OADMs. The dropping wavelength bandwidth of the OADMs was less than 0.7 nm, and the dropping wavelengths could be controlled precisely by adjusting the grating period.
