Integrated photonic optical equalizer
Real added value with LioniX international innovative technology
• Integrated photonic optical equalizer: A new era of equalization performance
Tele and data communications rely on the transmission of data through with limited bandwidth.
The low frequency parts of the signal can blur the boundaries between signal pulses, leading to problematic data errors.
Thanks to LioniX International novel optical equalizer (designed by Optagon Photonics),ultra-fast and highly reliable data-transmission
is possible. The equalizer, manufactured by LioniX International, corrects distortions and data errors in communications signals
and is the first such device to use photonic integrated technology to enable flexible operation across a range of data transmission speeds.
Optagon Photonics worked with LioniX international to create an optical equalizer in a compact Photonic Integrated Circuit (or PIC).
This PIC is the first optical equalizer to succeeded in directly mirroring the architecture and function of traditional electronic equalizers
— something that was previously seen as impossible.
Not only this, but the reduction in data errors demonstrated by the device is very promising — tests showed data errors reduced to
zero in all of the output signals evaluated, no matter how distorted the input was.
Additional benefit: A Low loss silicon nitride for high-performance equalization.
As equalization involves removing parts of a signal to correct distortions, the designers wanted to minimize the use of bulky optical
amplifiers and so needed to carefully control losses.
The valuable LioniX’s TriPleX formulation enables low loss optical wave guides and permits to couple to external light sources,
also with minimal losses.
Another benefit of this Photonic integration is flexibility, this compact equalizer can be tuned in real-time to operate flexibly with a broad
range of signal transmission rates. Data centre components may need to operate on different transmission rates and components may be
upgraded to enable faster transmission rates as technology improves.
This flexible PIC based approach to optical equalization therefore offers equipment manufacturers a one-size fits all add-on that can be
deployed with a range of components.
Furthermore, such a tunable device is future proof, with the scope to stay in use even as transmission rates increase over time(…)
• Other interesting topic about LioniX international advanced technology:
A photonic integrated ion trap used to create a scalable building block
for quantum computing rivalling the most sophisticated experiments.
A central challenge in quantum computing remains the creation
of low-noise qubits that can be scaled to sufficiently high numbers for useful computation.
LioniX has been approached to fabricate an ion trap on a photonic
integrated circuit (or PIC) .With this, the researchers could consistently
deliver light to exact locations in the ion trap.
This not only reduced sources of error and noise from free space optics
but also simplified operation — light could easily be coupled to the PIC
using optical fibers on the outside of cryogenic and vacuum equipment.
Using TriPleX™, Lionix proprietary silicon nitride waveguide technology,
issues are addressed by tailoring waveguides to optimize the properties
of the light at different stages. (…)
