Claim 15:
16. A method for optical buffering of an optical packet having an optical packet signal comprising:
providing an optical switch including a scheduler and a buffer, wherein the buffer includes a clock generator for generating a clock signal, an optical unbalanced Mach Zehnder Interferometer (MZI) and a fiber delay line (FDL) having an FDL length, arranged in a circuit;
configuring the scheduler to insert a optical packet into the buffer and to determine a number of circulations of the optical packet through the circuit;
using the MZI to modulate the clock signal based on the optical packet signal to create a reshaped optical packet after each circulation of the optical packet through the circuit; and
using the FDL to introduce a delay in the optical packet proportional to the FDL length.
