Abstract
Abstract—We propose a simple and effective scheme for alloptical
packet envelope detection (AO-PED), exploiting a slow saturable
absorber-based vertical cavity semiconductor gate and a
semiconductor optical amplifier. A high extinction ratio of 15 dB
was measured for the recovered envelope signal. The scheme is
suitable for photonic integration, and is transparent to the packet
polarization state and data rate. It also shows relatively low sensitivity
to the input packet wavelength compared to previous alloptical
schemes. AO-PED is experimentally demonstrated at 12.5
and 40 Gb/s; the recovered envelope was used to drive a 1 × 2
all-optical switch for low-priority packets deflection in case of contention
occurring between time-slotted synchronous packets. The
deflected packets could be routed to a buffering stage or to a different
path, depending on network topology, allowing thus contention
resolution without packet loss. Error-free bit-error rate (BER) was
achieved for packet payload data at the switch output
