Abstract

In this work, we present the design, simulation
and characterization of a frequency down-converter based
on III–V-on-silicon photonic integrated circuit technology.
We first demonstrate the concept using commercial discrete
components, after which we demonstrate frequency conversion
using an integrated mode-locked laser and integrated
modulator. In our experiments, five channels in the Ka-band
(27.5–30 GHz) with 500 MHz bandwidth are down-converted
to the L-band (1.5 GHz). The breadboard demonstration
shows a conversion efficiency of − 20 dB and a flat
response over the 500 MHz bandwidth. The simulation of
a fully integrated circuit indicates that a positive conversion
gain can be obtained on a millimeter-sized photonic
integrated circuit.
