Abstract
Optical spectroscopy is a well-known tool typically
employed for characterizing the properties of materials by
analyzing their iteration with light. One of the most spread
techniques is the dual comb spectroscopy, since it accomplishes
ultra-high resolution, and high sensitivity measurements with a
relatively simple platform including a single, relatively narrowband
photodetector. The employed optical dual comb can be
implemented through electro-optical (EO) modulation driven by
pseudo-ransom binary sequences (PRBS) at high data rates,
commonly in the range of tens of Gbps. For that purpose, the runtime
generation and transmission of adaptive PRBS is still an open
challenge, often involving expensive and not flexible high-speed
digital systems, with a few commercially available solutions that
sometimes do not match the application requirements efficiently.
In this context, this work describes the definition and
implementation of a System-on-Chip (SoC) architecture, based on
a FPGA device, capable of generating and transmitting two PRBS
for a dual comb, at a data rate up to 5 Gbps. The architecture can
be configured and its operation modified in run time, thanks to the
general-purpose processor involved, in charge of managing an
Ethernet link to receive new PRBS to be transmitted or set up
certain parameters. The proposed design has been validated
experimentally on a dual comb spectroscopy measurement, where
the absorption of a hydrogen cyanide (HCN) gas cell has been
successfully characterized.
