Abstract

High-speed communication between networks operating in the two transmission windows of silica fiber near 1.5 μm and 1.3 μm requires all-optical wavelength conversion between these two wavelength bands. To date, this conversion has been demonstrated only in a semiconductor optical amplifier with limited speed, a low on/off ratio, and a narrow-wavelength band of operation.¹ We demonstrate high-speed, broadband, all-optical 1.5-μm-to-1.3-μm wavelength conversion by using a nonlinear optical-loop mirror (NOLM).
