ASOCTM developed by Bookham Technology Ltd is based on Silicon on Insulator ridge waveguide technology. Bookham has demonstrated the low cost, high volume manufacturing capability of ASOCTM by offering a range of transmitter, receiver and transceiver products to the access market. This range was recently complemented by a number of products in the sensor and DWDM markets. Additional products are currently being developed which illustrate the capability of this technology to provide low volume, high functionality, highly integrated components. In this paper, attention will be given to the range of functionality offered by ASOC and their integration potential.
