Time-slot interchange of $40\mathrm{Gbits}∕\mathrm{s}$ variable length optical packets using conversion–dispersion-based tunable delays

Abstract

We demonstrate tunable time-slot interchange of $40\mathrm{Gbits}∕\mathrm{s}$ optical data packets using a conversion–dispersion-based tunable optical delay element. Odd and even data packets are extracted from an input signal, delayed relative to one another in a highly dispersive medium, and then multiplexed back together. Tunability is demonstrated by operating with two different packet lengths, 182 and $288\text{\hspace{0.17em} bits}$/packet, and a bit error rate of $<{10}^{-9}$ is achieved.
