LO-freeNo independent receiver local oscillator
SVDD system architecture
Reference light travels with the signal, so the receiver does not require an independent local oscillator (LO).
Photonic and electronic co-design
Co-designing a silicon photonic receiver front end with analog equalization for receiver-side polarization and chromatic-dispersion compensation.
Ultra-Low-Cost Coherent Architecture
Uncooled DFB lasers, no receiver local oscillator, and compatibility with direct-detection DSPs and components substantially reduce overall module cost.
