We describe the development of an optically clocked transistor array (OCTA) interface device for label swapping high-speed asynchronous burst optical packets. The OCTA integrates the three critical functions of serial-to-parallel (SP) conversion, parallel-to-serial (PS) conversion, and clock-pulse generation into a simple optoelectronic integrated circuit (OEIC) to create a single-chip interface between the input/ output baseband optical labels and a CMOS label processor. The result is a high-performance label swapping solution which is compact and low power. In this paper, a detailed investigation of the design and optimization of the circuit is first performed, followed by testing of device stability under subsystem operating conditions. Finally, demonstrations of single-channel switching speeds allowing greater than 100-Gb/s operation, 40-Gb/s SP and PS conversion with an eight-channel OCTA, and error-free label swapping of 10-Gb/s asynchronous optical packets with a prototype label swapper module are described.
