- Groundbreaking technology supports infrared and hyperspectral
image detection and sensing devices to view images more clearly, at
longer distances, and in low-light situations.
- In collaboration with UC Santa Barbara, experiment shows
first-time demonstration of a compact (micron-sized), monolithic
silicon photonic electro-absorption-modulator maintaining its
performance down to 4 Kelvin (-269.15 Celsius), enabling
transmission of signals at cryogenically cooled temperatures with a
compact, photonic integrated circuit.
- Rockley’s technology platform allows detection and sensing
devices to be smaller in size and weight, and lower in power
consumption.
Rockley Photonics Holdings Limited (NYSE: RKLY) (“Rockley”), a
global medical technology company focused on delivering leading
edge silicon photonics-based biosensing solutions by targeting a
portfolio of biomarkers, today announced a groundbreaking 4-Kelvin
performance demonstration with its monolithic silicon photonics
electro-absorption modulator technology that is key to the
development of next-generation cryogenic interconnect technology.
This advancement is intended to enable ultra-sensitive image
detection and sensing devices to view and capture images more
clearly and at longer distances, as well as in low-light situations
and enables these devices to have a significantly reduced size and
weight.
UC Santa Barbara’s project utilizes Rockley’s powerful
technology and will potentially advance detection and sensing
capabilities in devices for a range of applications that require
ultra-sensitive sensors. Possible applications include infrared and
hyperspectral imagers and cameras that are used for night and day
surveillance, aerial search and rescue, environmental remote
sensing and chemical detection, ultra-sensitive neutrino detectors
in particle accelerators, as well as interconnects for quantum
computers.
The cryogenic modulation experiment showed that the strong
modulation of Rockley’s silicon photonics electro-absorption
modulator at room temperature is maintained when it is cooled down
to 4 Kelvin (-269.15 Celsius, -452.47 Fahrenheit) with almost no
performance degradation. At these low temperatures, signal noise in
camera detector arrays is reduced dramatically, resulting in
increased sensitivity, and enabling devices or cameras to view
clearer images and the ability to see longer distances and in low
light. The ability of Rockley’s platform to maintain good
performance and capture data at this very low temperature means
that Rockley’s photonic integrated circuit technology can be used
to make these ultra-sensitive detection devices smaller in size and
weight, have a lower cost, and operate with lower power
consumption.
Rockley has collaborated with UC Santa Barbara to make this
demonstration. UC Santa Barbara brings their renown expertise in
photonics research to the collaboration by performing the
experiment that showed that high-speed signals could be modulated
and extracted out of a cryostat chamber at temperatures from room
temperature down to 4 Kelvin with minimal degradation of
performance. The results will be presented at IEEE’s Photonics
Conference on November 16 and subsequently published in the
conference proceedings.
“At UC Santa Barbara, our research is focused on closely
integrating electronics and photonics to push the boundaries of
speed and efficiency for the photonic links and optical networks
that data centers, computers, and sensors depend upon to share and
move data,” said Clint Schow, professor and Vice Chair of
Electrical and Computer Engineering at UC Santa Barbara. “We are
excited to collaborate with Rockley Photonics because our work in
transmitting signals via light at very low cryogenically cooled
temperatures will enable new technology that significantly
increases sensitivity in sensors, resulting in the ability for
cameras and devices to capture images with increased clarity.”
“Rockley has been innovating in photonics technology for many
years and I am not surprised that our pioneering work has generated
interest from academic research and other industries beyond health
monitoring and wearables,” said Dr. Andrew Rickman, chairman and
chief executive officer of Rockley. “I envision our technology will
have broader and important applications that will benefit
organizations and individuals around the world.”
“The ability of Rockley’s silicon photonics platform to capture
data at 4 Kelvin with good performance will lead to technological
advancements in image detection and sensors, including
hyperspectral imagers and cameras that are used by the department
of defense, defense and aerospace industry, NASA, and environmental
agencies,” said Aaron Zilkie, chief technology officer of Photonics
at Rockley. “Our collaborative work with UC Santa Barbara has been
key to show us how this technology has the potential to take image
detection to the next level and dramatically improve these
devices.”
