Multichannel optical add-drop multiplexers (OADMs) based on cascaded Bragg grating/Mach-Zehnder interferometers in silicon-on-insulator are reported. The OADMs are fabricated using electron beam lithography with a single etch. Three add-drop channels at wavelengths of 1542.5, 1557.0, and 1570.4 nm, each with a 3 dB bandwidth (BW) of 4 nm are obtained. All channels exhibit a transmission isolation of >20 dB, an interferometric crosstalk of <-30 dB, and a bandwidth utilisation factor of >0.5.
