Optical Signal Amplifying Technique
Institut de la Recherche Scientifique, Quebec City, Quebec, Canada
W
eak optical signals are common
in many science and technology
applications. However, they are difficult
to detect or process due to the incoherent
noise that is inherently present in any system.
PhD student Benjamin Crockett and
colleagues, working under the supervision
of Professor José Azaña of the Institut
national de la recherche scientifique
(INRS), have conceived a technique for
the recovery of weak, noise-dominated
optical signals. Their research was published
in the journal Optica.
This achievement is relevant to various
fields like telecommunications, bioimaging,
and remote sensing. For example,
there is considerable loss from long-distance
propagation through optical fiber.
In light-based biomedical imaging applications,
there are limitations for the
light power to avoid damaging the living
tissue. Similarly, in lidar applications (laser
remote sensing), high optical powers
can pose a threat to the eyes of a passerby.
In all these cases, the recovery of

weak, noise-dominated signals remains a
key challenge.
Lasers have enabled tremendous advances
in so many fields of research.
Yet the problem of sensitivity and noise
eventually leads to an obstacle for further
development.

in precision optical
solutions?
Most common approaches are ill
suited to retrieve a weak signal because
they either further attenuate the signal
or inject noise. The new method developed
by the researchers uses passive amplification
of the signal of interest over
the noise, enabling access to signals that
