Abstract :
A double-ion exchange process (potassium ion exchange with a subsequent silver ion exchange) is proposed for the fabrication of synthetic diffractive optical elements in glass waveguides. A computer-generated holographic guided-wave beam splitter with fanout to eight and 0.9 dB uniformity error is demonstrated.
