Government & Military
CeLight’s innovations in coherent optical
technologies, coupled with a unique, programmable, digital
architecture, enable breakthrough capabilities for advanced
military, homeland security, and government applications.
CeLight’s products and services enable
system integrators to offer solutions with previously unattainable
capabilities and improved price-to-performance ratios to the
end-customer due to two main advantages of coherent systems:
- Coherent signals use not just the amplitude, but also
the phase of light in order to convey and extract even more
detailed sensing information as a means to improve system
performance
- Coherent detection uniquely allows a linear transformation
of the received optical signal to electrical baseband so
that no information is lost, thereby allowing it to be processed
digitally as a means to attain new functionality and programmability
Over the last 30 years, $100B's have been spent in the commercial
and military markets to create and perfect technologies used
in the Radio Frequency (RF) domain for applications such as
communications, RADAR, signal intelligence and electronic
warfare. Key advances resulting from these investments include
the use of coherent detection and the migration of processing
of RF signals from the analog domain to the digital domain.
Yet prevalent optical techniques use analog processing, relegating
the optical world to where RF was 30 years ago, thereby preventing
the industry from leveraging its previous investments and
know-how.
Until now, that is. CeLight’s VectorWAVE technology
is uniquely positioned to provide a quantum leap by leveraging
the RF world’s accomplishments in coherent techniques
and digital signal processing to the optical domain. Just
like in RF, the VectorWAVE optical transmitter first synthesizes
the desired signal digitally. The signal is then converted
to an optical waveform and transmitted. The VectorWAVE receiver
is unique in that it uses coherent detection and digital signal
processing to analyze the received optical waveform. The use
of coherent detection allows the VectorWAVE receiver to filter
the desired frequency-slice from the optical domain and to
linearly convert it to an electrical signal that can then
be analyzed using modern DSP technology.

VectorWAVE Architecture
Recently, the U.S. Department of Defense and the Department
of Homeland Security have expanded funding to add the use
of optical frequency technologies to its product portfolio,
creating a whole new defense market for:
- Remote detection of explosives, trace gases and
bio-chemical agents – provides increased
homeland and global security against growing threats
- Secure optical communications –
providing a 1000x increase in communications link capacity
while retaining physical layer security considered mandatory
in RF links
- Coherent LADAR (Laser RADAR) –
reaching higher resolution for target identification, tracking,
and discrimination and identification of friend or foe
- 3D laser vibrometry – discrimination
of warheads from decoys for missile defense
- Optical signal intelligence - detecting
and analyzing communications and LADAR signals
- Opto-electronic warfare - jamming optical
signals and sending optical decoy signals
