C-Band 40 GHz QPSK (IQ) LiNbO3 Modulator
Description
The GKER Photonics C-Band 40 GHz QPSK (IQ) LiNbO³ Modulator is engineered to deliver superior performance in high-speed optical communication applications. Utilizing a dual parallel structure of Mach-Zehnder modulators (DP-MZM) embedded in a Mach-Zehnder Super-Structure, this modulator offers outstanding modulation capabilities. Each internal modulator features an electro-optic (EO) bandwidth exceeding 20 GHz, ensuring high-speed and reliable operation.
The modulator operates within the C-Band wavelength range of 1525 to 1570 nm, making it suitable for a wide array of optical communication systems. It is designed with X-Cut Lithium Niobate to achieve high bandwidth operation, exceeding 30 GHz, coupled with high extinction ratios and low optical insertion losses. Automatic Bias Control (ABC) is provided via a monitor photodiode, enhancing precision and performance stability.
Applications include advanced coding schemes such as OFDM, QPSK, and QAM, as well as carrier-suppressed single sideband (CS-SSB) modulation and FMCW LiDAR. This modulator’s robust design is complemented by its compliance with Telcordia GR-468-Core reliability standards, ensuring durability and reliability in demanding environments.
