LEO SPACE PHOTONICS
Integrated coherent receivers
Coherent optical functions on-chip
We develop silicon photonic integrated coherent receiver circuits for high-capacity laser communications. Our circuits indlude edge/grating couplers, MMI optical hybrid, Ge photodiodes and SiGe BiCMOS ICs monolithically integrated in a miniaturized form factor.
In ORIONAS programme, LEO and its partners demonstrated > 100 Gb/s coherent detection of single polariaztion QPSK signals.
Integrated coherent receivers
Patented integrated coherent receiver architecture
LEO Space Photonics is the assignee of US Patent 12,598,003 B2, covering a coherent receiver photonic integrated circuit with a single multimode interference (MMI) optical hybrid, non-intersecting optical paths and uniform electrical connections.
Single MMI coupler
A single MMI coupler acts as the 90-degree optical hybrid for mixing the received signal with a local oscillator.
Non-intersecting waveguides
Four integrated waveguides route the hybrid outputs to four photodetectors without waveguide crossing.
Balanced detector pairs
Four photodetectors form two balanced pairs and connected to SiGe BiCMOS through uniform lines.
