COHERENT DETECTION

Coherent modulators and receivers are key components used in today's optical transmission systems. Our integrated Indium Phosphide IQ Modulator enables 100G DP-QPSK and 200/400G QAM optical transmission for long-haul and metro networks. Our integrated coherent receiver based on silicon photonics is designed to meet the needs of 40G and 100G networks using coherent detection. Thanks to the SiP technology, our small form factor receiver (CRx-SFF) can be used in CFP and CFP2 coherent modules.

Both static and tunable dispersion modules can be used to emulate chromatic dispersion associated with transmission fiber. Low-loss dispersion emulators can be particularly helpful for dispersion ranges well above 10 000 ps/nm as seen in long-haul systems. Our low-noise semiconductor laser sources, such as the tunable narrow-linewidth laser, can be used as a local oscillator for multilevel modulation format transmission experiments using coherent detection.
