Abstract

We have demonstrated real-time decoding of 20-bit biphase-coded address header pulses, using stimulated photon echoes in a phase-matched crossed-beam configuration. This decoding is one of the functions required for coherent transient optical data routing, packet switching, and processing. The active medium used was single-crystal Y2SiO5 doped with Er3+, which provides an operating wavelength of 1536  nm.

(a) Temporal snapshot of the programming stage. For each header address, one spatial–spectral grating is stored in the crystal by a pair of programming pulses: a biphase-coded header address and a brief direction pulse. (b) Temporal snapshots of the processing stage. Headers coded with the addresses produce stimulated photon echoes in the spatial output channels that correspond to the directions programmed into the gratings by the brief direction pulses. (c) Phase-matching diagrams determining the wave vectors of the output stimulated photon echoes.

Schematic of the experimental apparatus used for address header decoding. An external-cavity diode laser (ECDL) operating at 1536  nm is amplified by an erbium-doped fiber amplifier (EDFA) and gated by three AOM's to produce spatially separated beams that are crossed and focused in the crystal by lens L. Stimulated photon echoes are detected on the two InGaAs photodiodes (InGaAs PD 1, PD 2).

(a) Representation of the header sequence in the processing stage, showing temporal ordering, spacing, and biphase coding of the header pulses. (b) Single-shot stimulated photon echoes detected during the header processing stage. Echoes are detected on channel A or B at a 3µs delay after the application of the corresponding header; this delay is determined during the programming stage by the separation of the header programming pulse and the header direction programming pulse. Weak cross-talk echoes are also resolved from the noise.
