Products | LiNbO3 Design & Fabrication Services | Consulting

CeLight delivers the value of digital coherent optical innovations to system vendors through its VectorWAVE-based products, sub-systems and integrated electro-optical components, customized design and fabrication services, and consulting and R&D services in coherent communications and technologies.



Three of the key building blocks of CeLight’s VectorWAVE platform are the Coherent Receiver CL-CR-10, Optical Hybrid CL-QOH-90, Quadrature Modulator CL-QM-12.5.

CL-CR-10 Coherent Receiver

CL-QOH-90 Optical Hybrid



The integrated broadband 90º optical hybrid, CL-QOH-90, can be used for coherent signal demodulation. The LiNbO3 integrated component accepts two optical signals (S1& S2) and generates four output signals: {S1+jS2, S1-jS2, S1+S2, S1-S2}. By attaching two balanced receivers to the output of the hybrid, the relative phase information between the input signals can be extracted via differential detection and digital signal processing.

CL-QM-12.5 Quadrature Modulator    


The integrated quadrature modulator, CL-QM-12.5, is designed for 10 Gsymbol/s Quadrature Amplitude Modulation (QAM) modulation. The device is based on X-cut Ti:LiNbO3 integrated optics technology. For the case of Quadrature Phase Shift Keying (QPSK) the device enables the transmission of 20 Gb/s with 25% super-FEC overhead.

These stand-alone components will also be marketed as part of a sub-system whereby they are packaged with electronics to stabilize and control the devices in order to ease integration into higher-level sub-systems and products. Initially, CeLight will offer four component sub-systems:

  • Quadrature Modulator sub-system
  • Optical Hybrid sub-system
  • Optical Comb sub-system
  • Coherent Receiver sub-system

For more information, please contact CeLight at


Over time, CeLight plans to deliver higher-level sub-systems that can execute advanced algorithms to provide value-added functionality. Systems integrators can use CeLight’s components and sub-systems to accelerate advanced application prototyping, development and testing for government and commercial markets. As the applications mature, government and contractor funding will support productization into deployed systems.
